Also like are there cases of people doing stuff that seems “Obvious Serial Killer Warning Sign”-y and Turning Out Okay?

Like the stuff the Texas Eyeball Killer and The Sacramento Vampire did before they started on the murdering (creepy taxidermy with terrifying button eyes and injecting himself with animal blood/drinking animal blood mixed with coca-cola respectively)?  Cause like people who do shit like that get released… these two particular people got released so are there cases of them like getting treatment, being medicated and ending up…okay?  I feel like there must be because otherwise no one would release them and I think true crime interest really warps your sample, y’ know?
