Suppose an evil and omnipotent demon informs you that he will perform a mind-swap between you and a stranger. Your memories, personality traits, cognitive capacities, etc. will be implanted into the stranger's body, and his into yours.
Now the demon gives you a choice. After the procedure, either your body or the stranger's will be subjected to unspeakable torture. It's up to you to decide which one receives the punishment -- your body implanted with the stranger's mental attributes, or the stranger's body implanted with yours?
Whose body do you choose to get tortured?
