I think it's actually difficult to know what you'd do unless you've been put in a similar situation. I know what I would like to do. But torture is very good at cracking a man, even those who are toughest to crack and we're only talking about the finite methods of human torture. Add that it's never ending. The pain will never stop. Ever. No moment of peace. For all your principles for all that you believe in and stand up for, could well be broken through torture just so that you bend to God's will. One might become vigilant and strong through human torture and have the will power to resist it to the very end (and it's a lot of willpower and no doubt some level of training). With hell, there is no end, no death, no heroes to save you, no mercy. It's a horrible and sick think once you start trying to think about it, trying to understand what it's like, but to be honest, that's very difficult.
Even though we cannot know a person's mind, I think it's a pretty bold claim to say you'd rather the torture, I think it's easier to make when you're not being faced with the situation.
This is why I often claim that God doesn't offer free will. In essence God only offers 2 choices because all your actions are only a means to your end and there's two possible ends. Eternal bliss or eternal torture. I would VERY much hate to worship such a God, I would have to lie to myself and delude myself into a state of mind where I am able to worship this God and live by this God's laws. I would feel dirty but would have to learn to deal with it and it might not make heaven blissful for me, but I'd have time to try and come to terms with that.. Although I have my principles, I suspect that in the end it will come to self preservation.
However, I have thought of something. Would one be able to meditate themselves into a state of self-hypnosis where you are detached from all pain? Would God try to break that barrier down to ensure your suffering.
