OP: Just add me to the growing list of people saying that you're not an awful person for wanting to date a blind girl, but the reasoning is funky.
One thing I'd like to add that nobody's mentioned yet, however, is the potential risk to the blind girl. It looks like there are underlying issues that you're hoping to solve by dating a blind girl. The thing that I would worry about is: let's say you do start dating her. What would you do if you still didn't feel better about yourself or about your neurology, etc.? In this kind of situation, it's very possible that you may melt down and take your frustration out on her, in an emotional or even physical way. That definitely wouldn't be fair to her, because frankly it wouldn't and shouldn't be her responsibility to fix that kind of need in you. This hypothetical situation may seem far-fetched, but it's actually not uncommon especially in cases where there is some element of power involved (e.g. you'd want a girl to be blind so that she can't ever physically judge by sight, as opposed to a girl who can see but chooses for herself not to judge by sight).
A thought question: if there were some kind of future technological advancement that would allow her to regain some or all of her sight, would you try to discourage her from getting the procedure done, because you would be worried that the relationship might worsen?
