I'm certainly comfortable with violent fantasy when the roles are acted out. This suggests to me that if I were convinced that certain person-seeming things were not alive, conscious, were not what they seemed that this might tip me in to some violent behaviors. I think at minimum I would experiment with it, try a slap here, a punch there. And where I went from there would depend on how it felt I suppose.

Also I would almost certainly steal more stuff if I was convinced that everything was landscape.
