Sure it's like that in fantasy, but suppose it happened in real life and the people simply lost control of their bodies.
They would still be conscious but couldn't in any way prevent themselves from eating you.
They would still feel the pain of you killing them.

Would you still do it?
I dont want to die, its as simple as that. I would try to avoid killing unless its absolutely neccesary but if my hand is forced i would do whatever it takes to survive.
