There was this series on Danbooru named 'Reactions of Abusing your Wife'. Or something..
It was horrible, but interesting to go through.
Maybe the artists that made them for sadism, but I used it as a call for help. Imagine you see this poor girl beaten and abused. I feel the need to help and patch her up.
Only problem is the focal point is the viewer IS the abuser, not a third-party.
Oh well...
There was another pool called 'Reactions on Praising your Wife', which is far better. Now that series makes your feel good being the viewer.
