I feel as though that people were so focused on hannah, the tapes and almost her story that they didn’t take account other students like Alex. He was clearly hurting or suffering some kind of pain and there were small hints as to what he was feeling like:
Alex tore down the posters about suicide and said “this is clearly an option”
He had chosen a suicidal song to play with the band
He said to Justin “if i kill myself, you die too?”
He said more than once that life sucks and that he’s the reason for hannah’s suicide.
Maybe if everyone wasn’t focusing so much on hannah that they would’ve noticed Alex’s cries for help and could’ve prevented a close suicide
