I enjoy sex with pretty college girls. So did Ted Bundy. I don't feel any need to give him sympathy just because he and I have a motivator in common.
Plenty of people get divorced, get screwed over, are generally angry at the opposite sex and the courts and feel mistreated. I can sympathize, but my sympathy ends when they kill their ex-spouse or the judges and lawyers who were doing their jobs.
/out/ could and should pick far better heroes.
