I dunno... None of my characters are really evil.
Sure one of them has his psychothic nature and needs to get his fix of serial murder every once in a while but I don't consider him "evil" really. >_>
Anyway, to explain him then.
This guy wants to be the hero, goody goody two shoes, but he has a dark secret.
He needs to satisfy his hunger of murder.
He has a ritual he needs to perform once every week in order to not lose control and just murder randomly.
The ritual is that he needs to find someone he considers evil, the longer he wait the lower the standard becomes.
To the point where someone can say "Piss off kid" and he just goes ballistic.
After he's chosen his victim he will stalk him until the right time.
When he's about to strike he will knock the victim uncounscious(?) then line up various toys around him.
When he wakes up he will stab him to death with a gruesome machete and afterwards eat him.
Sure he might seem like an evil bastard but he's more of a vigilante.
Taking care of the wasteland scum in his own way.
He will still only do good quests and will never hurt an innocent person unless he's gone two weeks without his ritual.
He's a friendly, charismatic and very noble person, just has a tendency to murder and cannibalize people as well. :laugh:
AH straight from the show "Dexter" -minus the wasteland part. Season 5 is almost out
