Didn't Loki have an eternity of jealousy and neglect going for him before he went evil? That's way better than "I'm suddenly insane now because bullying and also disfigurement". If anything, Jeff the Killer is Alan Moore's Joker from "the Killing Joke": a normal dude has a bad day, and goes instantly crazy and evil. Totally illogical. Tim Burton actually did it better, because at least his Joker was already an unhinged asshole before he fell into the goop; his physical scarring just made him explore his creative side a bit more.
