You're advocating for arbitrarily cruel punishment that is out of line with sentencing guidelines in the US and international human rights conventions more broadly.
Given that, I'm asking where you draw the line when it comes to "violence" and if you'd be satified to see significantly more people imprisoned for life.
As far as it goes, I think conditions in prisons should be far nicer than they are now. In these days of videoconferencing, it needn't be very different than lockdown. I don't believe in punishment; I believe in permanent removal from society.
