It's ok for two different things to both be bad, we don't have to pretend they're the same.
For example, Manadel al-Jamadi was murdered in detention, while being tortured by the US military. The people who murdered him then took "thumbs up" photos with his corpse.
No one was punished for his murder.
NSFW, his corpse is pictured on this page: https://en.wikipedia.org/wiki/Killing_of_Manadel_al-Jamadi
People in power will abuse power. That’s inevitable in any regime. What makes the difference is how they are held accountable, especially by their own regime.
