I think it boils down to this: It takes far more work for a generally bad person to purposely turn their life around than it takes for a generally good person to accidentally screw up badly. A bully is always going to be a bully unless they have that elusive "come to Jesus" moment. And thereafter, it takes just as much effort to demonstrate that it even happened at all, and that it'll stick. It most often doesn't. And people that know the person in question have seen it over and over again. "and I probably was pretty awful to this girl." Exactly that kind of weasel wording suggests to me that this person is, as you word it, a dick. If she traumatized the other girl so badly that she would quit upon her hire, she'd totally remember why. Unless of course she was such a "dick" to everyone that she just assumes the role without even thinking about it. In both cases, she got what she deserves. It's just pathetic whining about it now, since she made herself the "victim" through victimization of others. She could always do what other people rejected for being useless do: move to a different place where they don't know you are like that.
