Picture this: you're an 8 year old Adolf Hitler. You're minding your own business when some asshole rips a hole through time and space and starts taking potshots at you while shouting "This is for the Jews!" Now you see why Hitler tried to wipe them all out. To prevent that from happening.
Look, you can go to a hospital and deal with the nurses who are high on oxy and the doctors who are one more dead cancer kid away from going postal OR. Or hear me out. You let me work my literal magic and cure you.
