I'm not exactly sure how relevant this is the the free will conversation, but it's related and something I think about on a regular basis.

When I see a person who grew up in a wonderful environment with presumably good genetics, judge and condemn someone who did not, I wonder how they justify their superiority. It's as if they believe that, if they were that person, they would make better choices and do better things with their life. My question is, if you were that person, with exactly the same genetics and environment, then wouldn't you, by definition, BE that person and live your life in exactly the same way?

I suspect their answer would eventually come down to something about a "soul" which, even if it exists, would still be something that you were born with and thus completely out of your control. So, again, I would ask how they deserve their superiority, especially if they don't go for the soul argument.

I can then imagine some of them going for the "I deserve it because I was so awesome in my past-life.", which also doesn't hold up because it's a circular argument. So, again, how can they justify their superiority?

I'd say it's just luck, but I can see some people using that as an excuse to never do the right thing. "I was born this way so that's how I'm going to be." I could probably argue with myself for hours about this kind of stuff.
