You say this until it hits you.

But hey, you don't seem to be very empathic about your luck in life.

You could have been just the person in prison.

Btw. some religions believe in rebirth, you might become a prisoner.

Some believe in an infinite rebirth of universities, which will lead you to be in a prision in another reallity.

Even on a logically viewpoint it would be better for your 'other lives' to not be cruel to other human beings.
