He's not crazy. He's autistic. That makes him very valuable (as can be seen from his exploits). If you can work out what makes him tick, you have yourself a very powerful weapon.

This is a bunch of crap. Autistic people are not "crazy", we just don't follow the same asinine logic you "normal" people do.

What he did isn't even some great big evil thing, he just hacked some corporations. There are plenty of neurotypical people who do the same thing. Governments too. A decent chunk of the world holds these entities to be pure evil and view attacks against them as totally within reason.
