1. It depends what other details related to other people might be leaked in said confession. Pissing off the wrong people could make life in prison that much worse down the line.
2. Is neither an acceptable choice? Everyone else seems to be copping out of this one.
3. I'm leaning toward living forever, but I question the parameters. Do you still physically age? Are you immortal in the sense of being unable to be killed? If your head were lopped off, would you just be a talking head for the rest of your life, or would you be able to regenerate, reattach, be invincible to harm, etc?
4. Demon. The life of an angel is the life of servitude.
5. Politician. MY views being successful would be very amusing.
I would ask a similar question and get a whole other answer, I think. It is weird to me. Another, realistic question is why do some people choose to be "put out of their misery?". Take beliefs and mumbo jumbo out of it and you would be saying you would rather not exist than still be alive, even if it is a life of pain. It would not be like you could change your mind later.
