Totally opposed to capital punishment, but as long as the person who enjoys the work isn't the person who decides that it needs done it seems fine, maybe even better if they enjoyed it. You probably want the person who isn't going to get PTSD from it carrying it out if minimizing human suffering is the goal.
I can't decide if doing the same thing with pedophiles and CP moderation is terrible or not. My gut reaction is terrible but after hearing about how traumatizing it is for the people who do it maybe it's some kind of fucked up win win. Because I could straight up not do that job, but that job being done prevents real life abuse.
