Dear me, i'm gone for but a few hours and things have escalated. Honestly though, I can see where both of the parties involved in the argument are coming from here. On the one hand, BK feels as though an idea that he's worked on has been plagiarized and altered to fit something not his own, but on the other hand Sauron's options as far as a demon's backgrounds appear to be limited to but two options for the origins of his character's demonic nature, henceforth he made the best of what he could by blending both ideas for his character's creation as well as adding in an idea from another character. Now then, as far as i'm aware, the ideals of hell/hades are similar to that of a prison depicted in fiction, in that the only way to gain power or prove something (in this case, superiority) is through a show of brutality, so it isn't very surprising that both characters muderhoboing their way through swaths of demons would result in attaining higher status. The only important thing here is the reason for the murderhoboing, which clearly differs between characters as BK stated that Maverous killed to prove superiority and Sauron stated that Zaziel killed out of ingrained instinct/training and a burning desire to find his purpose.
