I'm fine with war crimes being committed; plunder, killing people who surrender. Those will be the primary crimes I'm willing to allow to be written out. Others will be implied are stated that they happened, but never shown. As such, I don't really want to see exactly how your character skins a pyjak while keeping it alive.
We are not quite going that dark, I will draw the line at sexual things. So no to that kind of experiment all together. When I mean dark, I mean more war atrocities kind of dark and nothing more for now. Sexual stuff though, no (primarily rape or abuse in the sexual regard) is a no.
