To be honest, I wouldn't really care. Its not in my power regardless of what happens, if I were to somehow have no freewill, I wouldn't know it. The analogy of the man in the room suits this well: ( it goes a little like this )
A man wakes up in his room, hes just slept and decides he isn't going to get up just yet, so goes back to sleep, he thinks he has a choice, but he didn't realise the door was locked and couldn't leave if he wanted too or not.
I'm sure if we don't have freewill, it would be similar to that.
The higher power thing just seems to remove responsibility, in the sense of God, it seems to remove morality, or whats good or bad. Such as, being scared of someone so you decide to be "good" because of him beating the crap out of you or punishing you isn't reinforcing why you should be good or bad. All its doing is telling you to be afraid. That isn't a good morality.
The third is how I see life. Simple, my life is unimportant, I'm tiny and insignificant and it doesn't matter what I do. I'll cease to exist one day. It sounds a bit grim but its not really, because I know my effect on other lives could make peoples small life on this earth a happy or sad place, and I choose to be empathetic and care about those, and to make a positive impact. Thus, better morality.
I'd agree with loki on this. Perhaps we really would be at our happiest under rule. Then again if all people knew that for a fact on 3 then that would be good too, religion brings so much suffering to this world it's insane, you don't belive this well you have to die, of so your a woman thats nice now do what the men say, oh your gay your an abomination. I mean come on.
I think 2 is the best, because Free Will is something everyone should be given a chance with in my opinion, but doing bad things gets you punished by this "higher being". It's quite similar to this world except it's more like 2A because, so far, no higher being has come to punish us.
As for the others, I don't think the concept of "free will" makes any sense when you get down to it. My choices are never free; they depend on my knowledge, personality, current senses and whatever else is going on inside my brain, and if you could completely recreate my brain state, then I think I'd make the same decision again (unless it was truly random). So I don't think free will even makes sense, because there is no explanation what part of me, exactly, does the free choosing.
