Re: In hindsight what changes would you do
You know what, that's a valid interpretation. But I think it's arguable that your interpretation (that everything was okay all along) has some conjecture to it as well. But both of ours are coherent interpretations, depending on how you read into certain lines throughout the movie.
I think it's a bit of both ultimately. I agree with what you're saying about him wanting to survive and fight first, with a potentially secondary death fantasy in there. That's how I view it. It's not something he's really conscious about, I certainly wouldn't call him suicidal by any means. But I feel that on some level it's there because I believe Alfred does understand Bruce better than anyone, even himself. And in TDKR, that is the thing that is making him weaker, it's the thing he must overcome. Even if it's the faintest little thought in the back of his mind, he needs to be fully committed to living if he wants to come out on top in the fight of his life. He needs that extra push.
