If you find psychology and stuff like that interesting or if you liked creepy and or fucked up shit i highly suggest the 1989 doco "child of rage" about Beth Thomas, its interviews of her with her psychologist, she was abused at a very young age before being adopted so she was essentially a child psychopath who didnt feel and wanted to harm and kill her family and animals super super fascinating she got therapy though and is now a successful nurse but its just one of the most interesting things ive ever watched
