You're welcome, Ghostdancer and thank you, Hallow. =) I've seen that movie too - eep!
What we might percieve as 'evil' in Ed Gein's case (or any other, as far as that goes) may really just boil down to mental illness. I don't claim to know what makes these guys tick - or how, precisely, they came to be what they are/were, but the mind is a vast frontier and we don't even know the beginning.
Which reminds me - and not to get off topic - but John Wayne Gacy's family asked that his brain be examined (post-mortem) to see if any 'differences' could be detected. Nada. Looked like any other healthy brain.
