Do girls just settle for nice guys in the end?

Scenario begins, as they so often do, with a young and nice girl first becoming attracted and involved with a known player/bad boy. Turns out she discovers that his type is not very healthy for her, she leaves, and decides a nice guy is best for her.

So, my question is this. Did this girl end up settling with said nice guy only because her first and most natural feeling choice just wasn't good for her?

If it ever worked out with this bad boy for some reason, do you think this would impact her romantic opinion of nice guys in any way?
