Why is he a victim? He chose to make his identity known to people! He attended Reddit meetups. People knew him.
Was he not aware that he was trolling and doing nasty stuff? If he was unaware, then I can understand him feeling like a victim; but he was fully aware that his actions were considered abhorrent by many people, and still persisted. So, naturally, people want to know who this person is, what makes him tick, etc.
