I don't feel so bad about thinking that the folks who run them are probably the bad guys and are literally evil. Kind of like reading histories of the CIA.
And the more evil they create the less I feel bad about not being okay with the larger governmental entities that operate them.
For a long, long time, I felt like a whiny teenager, being pissed at my parents. As I get older (I'm 45 ish), the more I feel like my disgust at the folks who run these things is an actual ethical stance.
The people who run prisons in the US are literally evil.
There may be literally nothing to be done about that.
But that fact doesn't make the people running those prisons less evil.
