All i got to say is this -__-. You knew what you were doing, no one put a gun to your dome and said do IT OR ELSE!.
Look, it's not good that she committed suicide, it's not awesome that some kids decided to bully her. However if this dude knew his SISTER's friend was on brink of committing suicide, maybe the parents should have known? Maybe the fact that if she was having issues and everyone else knew about prolly should have helped her? Either way I feel this shit should stay off the forum because all it's gonna do is cause drama.
