Hrm... I think I am still a bit confused over what makes demons tendenced to generally (though not always) obtain mindset that might fit the general perception of evil, and gods one that might fit the general perception of good. Their instincts, which you referred to? Something about how the seeds were made by the respective spirits? If their drive makes them more likely to do things of a specific kind, then the drive probably has some kind of preset?
Ah, there's actually something like a story to why that is on top of an explanation. If you recall the ancient history of the Planes and how the immortals first came to be, it all started with the Grand Master of Evil, the first immortal and demon lord, a being that was not created by the Spirits and the ideal that laid the foundation for the creation of the other (original) demon lords. When Ismyel decided to try to replicate the Grand Master she forged completely new Seeds of Evil to richly infuse with her essence until she forced the occurrence of powerful immortal life; these demons were created entirely by Ismyel's design and shared her view on what evil was, and thus there was not much variation among them in terms of personality. This is why most of the demon lords seem archetypically evil rather than evil per an individual definition of the term, although some of the lords that came later on, such as Valderoth and Kreshtaat, and the eternal exception of the Grand Master all go by their own unique perception.
After Ismyel had created the demon lords and discarded them as being less than equal to the Grand Master, however, these demon lords went about to increase their own numbers, and they did so by hunting down mortals and ripping the Seeds of Good from their hearts, only to then infuse them with demonic energy; this was all before the afterlives had been introduced, and thus it could be done. The result of this was not more demon lords, though (clearly one demon lord cannot form another), but the first lesser and greater demons. To counter the demon lords the Spirit of Good then went and collected a number of the discarded Seeds of Good ripped from the mortals-turned-demons and infused these with its essence until they became the original gods, which then went out to turn the remaining torn-out Seeds into angels. See, while the original demon lords were created entirely by Ismyel's will, all gods that ever existed were always made from fragments of existing beings, which is why there is much greater difference between their perceptions of the alignments than with the original demon lords as they inherited parts of the being their fragments came from.
Is there a common preset between these? With some of them; the original demon lords shared the preset that was Ismyel's perception of evil, but beyond that they all inherited their perception from their origins. Under greater scrutiny you would probably have a hard time finding a god that adhered completely to the general consensus on what is "good", and it would be equally challenging to find a demon lord not among the originals - or even among those - that suited the popular opinion of what was evil perfectly, either. If any such preset exists, it would be in the form that Spirit-born deities also inherit part of the Spirit who made them, but as soon as they have components to them that did not come directly from the Spirits of Union they immediately deviate from that preset.

Do mortals get their seeds of the opposite alignment expunged when they get turned into demons or angels?
In a sense they do, although the process is not as simple as the deity facilitating the transformation just erasing the unwanted Seed. The Seeds of Good and Evil cannot just be destroyed by any normal means, you see, and even if a Seed was removed from the being it belonged in, it would continue to exist on its own in some manner or form (they can degenerate over time if left on their own like that, though, but that's another story). Rather than removing one Seed from dead spirits desiring to ascend to immortality, it is more a matter of their Seeds being fused together into one, which, as is so often the case, the two opposites cancelling each other out upon fusion and annihilating each other to an equal degree. The Seed that has been grown more is always the one to survive this fusion, since by the time it has completely cancelled out its counterpart it will still have some unfused growth left, though typically far less than it had before the fusion. The energy released due to the annihilation of the Seeds is part of what feeds the increased power of an immortal compared to a dead spirit or mortal, though this energy can only be contained in an amount proportional to the uncancelled growth of the newly ascended immortal's remaining Seed, meaning that the more good/evil they were before ascending, the more power they will be able to harness from the process.
Demons usually leave it at that (which is why their demonic manifestation and power-level is usually a product of how evil they were before ascending), whereas among angels the gods tend to gift them whatever power they lack so that they can manifest in accordance with the most fitting personality-archetype among the angels rather than in accordance with how good they were. There are always exceptions, though... there are demons that were so evil before ascending that they evolve into unique entities rather than manifesting as known types of demons (these are the ones termed "greater demons", which refers to demons of orlgarhi-level power and above), and contrary to what most mortals in Reniam think it is not only demons that are divided into three tiers like that (lesser demon, greater demon and demon lord); angels also have individuals so good that their initial amount of power from the fusion of Seeds is even greater than that of other angels
after having been gifted additional power by their god, and these angels are the ones that fill the tier between regular angels and gods; archangels. Eh... but I digress.

Why do plants not qualify as mortals? I recall their souls are typically more placid, and that in this world a plant-soul can reach over multiple individual plants (though wouldn't it make them one person, rather than not mortal? what about colonial animals, especially the lesser ones?). Real-life plants typically communicate chemically (and while some of them work together, even across species, they more commonly try to kill one another off). The changes of a plant's chemical composition can also be insanely fast.
Plants do not qualify as mortals because they fail to meet two of the three criteria that determine what a mortal is. Plants do not have Seeds of Good and Evil, which is also one of the main reasons why they are considered firmly under Gaia's domain as the Spirit of Neutrality; the only kind of alignment they can have manifests when they merge with Living Woods, and even then they do not have Seeds, but only a "memory" of the Seeds of the mortals whose energy facilitated their ascendance. The other failed criteria is that they do not have
independent souls, but rather share one big, organically fluctuating soul with other plants in the area. Even though plants do have awareness and are capable of communicating, and when becoming Living Woods can even be considered equal to or greater than typical mortals, they are not mortals. Eh... well, to be fair I suppose they could be considered as adhering to that second criteria by citing that all ambient energy is technically an extension of their soul, but that would mean that the soul of plants is actually the soul of the Plane of Reniam itself rather than just plants, which would be a justifiable way of looking at it, since ambient energy in Reniam always carries some memory of the plants it has been through. It's start to get really philosophical from there, but suffice to say that whatever plants are, especially if they are the soul of Reniam itself, it is not mortal.
As for colonial animals... if they have any kind of awareness and capacity for fundamental thought at all, they qualify as mortal with all the perks that come with it. Generally speaking things like amobea and bacteria and such won't be included in that due to their inability to have independent awareness and are, in this universe, actually counted as part of the same soul-structure as plants rather than being considered mortals.
