Just referring to some Dahmer case analysis , it said “ you don’t just grow to be 18 and suddenly become a sexual sadist and serial killer”.
He had normal issues growing up, father away a lot, Mum a little bit crazy ( in a nice way) a younger brother who he resented.l for getting ting more attention.
But those things happen in many families. Evidently he had a super charged libido from a young age( 13) and was planning to attack a jogger with a baseball bat.
Don’t doubt your comment that he loathed homosexuals but was one himself so obviously mentally screwed up about his, and others, sexuality.
The fact that he kept body parts etc indicates a desperate loneliness for company, which evolved from his childhood where he had no friends.
Just a bit more interesting info about him . I guess it’s hard to wrap our heads around what he experienced and the outcomes.
