Sadly, it's a bigger problem than just republicans. There's a scary number of people that will say "good, they deserve it". The US parties aren't the same on many issues, but both of them push for overuse of the justice system for punishment and not rehabilitation. The overwhelming consensus of American voters appears to be to use jail/prison to punish people, not to actually solve any issues with crime.
Just look at any big thread on topics like this and you'll see plenty of people acting like this is a good thing. And whenever some horrible person goes to prison, there'll be tons of comments of people hoping they get raped, tortured, or even murdered in prison.
It's not even unique to Americans. I see this all the time from my fellow Canadians, too. A significant number of people just want everyone in jail/prison to suffer.
Y'all, that's what US prisons always were. When I was growing up in the 'naughties we regularly joked about prison murder and rape and the many inhumane indignities prisoners face. That was just "normal" for kids. Prisons have always been death camps.
Climate change is just creating another way to torture people to death.
