Societies have locked up or otherwise punishing anti-social elements for most of recorded history. And every society, no matter how extreme the punishments, has still had anti-social elements. So, instead of marking those elements as even less part of society, maybe the way forward is inclusion.
Certain types of psychosis and neurosis will potentially lead to anti-social acts. But most anti-social acts are committed for a reason other than not being able to see they are wrong; so why wouldn’t we want to listen more to the experiences of those who aren’t currently fitting well?
