Issei Sagawa. A cannibal who was caught in France and pronounced insane; however, after going to a mental asylum in Japan, they declared him as being sane, and he checked out straight after. He’s still free to this day if I remember correctly, and in interviews has stated that he may kill and eat human flesh again. While I was watching the interviews, I felt beyond unsettled. Really doesn’t make me feel better that he’s still out there.
