Hello! I was wondering if I could get a bit of advice concerning a character of mine. The thing is, he has no conscience whatsoever. This becomes a problem because while he doesn't have a conscience, he does know right from wrong. Ah, it's hard to explain... He can do something bad, and while he knows what he did was bad, he doesn't feel any guilt. Do you have any tips for portraying this sort of character without making him seem too erratic in his actions/motives?
