I do find your comment quite judgemental and vengeful. I'm not condoning his actions, but simply saying that I think we benefit as a society more from learning from this man, including learning from his behaviour rather than spending our energy and resources hating on and wanting to punish someone for essentially an act (excluding the death) of which had no effect on the people being watched.
To punish him in my mind is to say that we should keep these things in the closet (or attic in this case), and the lesson from that is only to hide what really goes on in the world instead of sharing what really goes on. I'd rather know about this and encourage others to share their stories.
