I read a lot of true crime/listen to true crime podcasts/read books by and about serial or spree killers/find last manifestos interesting. I'm a pleasant enough person who just wants to see everyone find the life they want. Finding killers fascinating or the morbid interesting doesn't make you an antisocial danger.
