Bad for whom? If you have the two options:

(A) Bad for people causing negative externalities.

(B) Bad for people causing positive externalities.

I will choose the former over the latter every time. Sure, it's bad for the kid to be getting abused since they're expelled from school, but it's bad for the kid to be getting abused since this other kid wasn't expelled from school.
