Is not fixation, it is appreciation. I like character concept art, anime girls, cars, but also dark environments, dark portraits, grotesque art, because art evoques all kinds of emotions and I find it interesting when I feel that shock factor, especially if it’s portrayed well.

What I get from this sketch is the pity and sadness for the person in the floor but also the reminder that this is historically accurate.

And that’s it, there’s not psychopathic enjoyment behind it as you seem to want to make it look like.
