Does some people deserve a shitty life, in general that is not something we should strive for.

There are two things I feel about this, first is prisons as they are in many countries are really bad for the employees, lots of suicide etc. As a prisoner being put away for years with minimal contact with the outside world is a really heavy punishment even if you live a life without constant fear.

A society that mistreat people is not something to strive for, and making prisons as bad as they can get will affect society as a whole. Paying prisonguards a little extra to take the risk of suicide seems really rotten to me.

Edit: this extends to warcriminals.
