Isn't the BoVD 3rd edition?You might need to do some serious updating to get it all the way up to 3.75.Also, with those alternate curses, a lot of them have the undesired effect of hurting bystanders without giving those bystanders a defense. That means, when you cast bestow curse on level one peasant... suddenly, you've mind controlled the next opponent you face into wasting his first turn on the peasant, regardless of how good that person's will save is.
I'm not sure what version of the curse or what odd twisting of events could lead to that effect. The only curse effect that I think you could be referencing is the one the next person they meet hates them, but that doesn't force them to attack them or anything. Not to mention, you'd have to drag the peasant around so that you could suddenly throw him out to meet your next opponent, while keeping him sealed off from interaction until then.
Also, to balance a lot of those things, all the DM needs to do is allow saves for the secondary targets involved. Pretty dead simple to house rule, actually.
I do see Sujurak using evil spell components when he can, though. He's got claws as a racial weapon, if an enemy humanoid is already dead he could be pretty quick about tearing their heart out (probably a Heal skillcheck, can be done untrained to pull it out without damaging beyond use as a spell component) or carving off a finger to use to try to modify a spell.
Also, the willing deformity feats and vile magic / just dark magic in general are awesome.
