You know it could just be that the guy is nice and doesn't like seeing women being abused. Put that as a mandatory 4th option since without it he'd just be a rapist (need to feel powerful, need for blood and sex? Yeah, recipe for being the guy who put the damsel in the tower, not the handsome prince).
And I'm perfectly good with saving or being saved. Heck, my mother has fixed loads of problems for me throughout my life. And I've fought for her whenever a guy got violent towards her. I think it's more about doing what you can for the people you care about. Damsels just can't do much.
In all of the universe there is only one person with your exact charateristics. Just like there is only one person with everybody else's characteristics. Effectively, your uniqueness makes you pretty average.
