I don't go gunz plazing nuts from seeing Geromes hugely controversial paintings is more what i'm trying to say. He wasn't pushing it with making it just on a few occasions and i doubt many people who paint vile things enjoy doing vile things. Objectifying women, or men, doesn't really count as weird ideology i guess, as long as it's balanced and for the sake of art and entertainment.
I tried making a funnay with calling Gerome a possibly vile man, but failed, obviously.
When i think about it, if there really was someone who painted extreme violence cause they enjoyed doing it so much, it would be quite fascinating, though it's more likely that the artist was just fascinated about it himself so he painted it.
I might be confused about what you're getting at, but would anyone ever paint someone being beaten and raped if they didn't like something attached to the thought? Or someone could find it completely repulsive but painted it anyway cause it causes interesting emotions. All for the sake of entertainment of course.
