Disagree with this. If the only way they can be released is doing this, then keep them in prison.
If they are a zero risk, the government shouldn’t mutilate people. If they cannot be released without that mutilation, they should remain behind bars.
If that means life, it means life.
Agreed, either lock them away or don’t. Releasing someone you think belongs in prison and giving them even more reason to hate society from their POV is hardly sane policy. Its feeling good rather than doing good.
