There's an interesting scene in the Psychopath Night video (about 38 minutes and 34 seconds in) where Kevin Dutton asks people what they would do in a particular scenario:
"Imagine you're in a room with a newborn baby and the baby is laying in a cot fast asleep. And you have to believe me when I tell you this is true okay, this is just for a thought experiment. You have to believe me when I tell you that that newborn baby, when he grows up, will grow into Adolf Hitler. okay. You have got a pillow in that room and you've got 2 minutes. When you walk out of that room, is that baby still alive or is he dead?"
I'm curious what choice you would make and why.
