What about people who work in slaughterhouses? Or a coroner or a mortician? Are they inherently "unhealthy" people because they have the personal temperament to handle a job that involves a lot of close contact with death? All nasty but necessary jobs with probably a lot more PTSD risk/scale than occasionally watching some gore and having to identify if someone's use of a racial slur violated community guidelines or not.

No, it's like having someone a poor sense of smell detect which things smell and which things don't.
Not to mention, having them do this work is taking advantage of a dysfunction rather than helping to address it. In fact it would be likely to make the dysfunction worse.
So watching the destruction of human life and/or incredible suffering of other people is not problematic to you? If someone has a dysfunction is it not cruel to take advantage of the dysfunction, whatever benefit might be derived by others? Seems like the very definition of dehumanizing rather than caring whether or not your fellow man is thriving.
I'm not saying force these people to work, simply that they're people who lean more to the callous side of the emotional spectrum and they're better suited for this kind of work.
What you see as dysfunction, their apathy when viewing bad content, is their normal state of being.
