Of course there is. Freedom is a pretty fundamental human right. We don't mind taking it away from some people, sometimes permanently. Then of course the death penalty is a thing.
Now organised abuse, or even not taking steps to prevent such abuse is accepted to be a bad thing by most of society so that shouldn't happen. But my concern isn't directed in any way towards violent gangsters that held an entire country hostage.
And why mention that inmates have forfeited their human rights if you see no evidence of abuse? Weird thing to pre-argue.
