There's something psychotic about harassing someone you know for YEARS, anonymously, in such a vicious way as he did. It's just cruelty on a level akin to torturing dogs for fun. "It was kind of a game" is hardly an excuse. "I will kill you, I will rape your wife, I will do <unspeakable things> to your wife's dead body..." Sending ashes. Putting dead flowers on the door step. Causing the man to be paranoid in his own house. Causing him to cry over the safety of his family. This is beyond harassment, and lasted daily/weekly over a period of years.
I almost don't believe this is real. How could a psychotic 17-year old be let off with a handshake and a look in the eye? He's going to kill someone someday. I'm stunned.
