If a troll knew that someone committed suicide because of their harassment do u think they would stop, or do you think their mentality isnt like that?

Someone I used to know on a site a little like this committed suicide about a year ago. I can't say I really knew him that well at all, but mutual friends who did said that the discussion after it happened was callous beyond words, and virtually everyone was joining in. It was almost a gleeful thing for them that someone had suffered so desperately that they took their own life.
