Banning is a horrid idea. How will people know what behavior to watch out for to prevent others going as insane as he did?
My gadz, everyone knows if you tell a child (weak minded/not fully developed) they can't have/see/watch something they will seek it out - BUT not have the parent there to put things in perspective, thus forming crazy opinions that can lead to badness (see most any episode of southpark).
It's better to have public discussions on the problems the person has.
Look at all the years of trying to mute drug problems, it only got dramatically worse. Now people are more interested in preventing and helping with recovery from addiction, than ignoring the problem - which made it worse.
If society doesn't learn from these situations, they will reoccur until it does.
