I'd have to say Zsadist from "Lover Awakened" by J.R. Ward and her Black Dagger Brotherhood series. I think I'll always love him. Such a terrible backstory and real issues!
While an alpha hero is almost always hot, I think most women would like to have that beta hero every so often. They tend to be kinder, more considerate and sometimes that's exactly what us girls are yearning for.
Alphas are often leaders, therefore others depend on him requiring his time and attention. Betas are more often able to put their lady first in their life because they don't always have the same level of responsibilities you see with alphas, at least as portrayed in a significant portion of fiction.
So yes, I love the alphas but sometimes the nice-guy-beta is just what I need!
I can't say that I've ever wanted to kiss a guy I've also wanted to beat over the head but you certainly make it sound like something worth thinking about (and maybe trying!).
Hey, if you get to experience your imagination that well and still realize that it's not reality, then I say enjoy it. Why not? You get to have a lot of fun and nobody gets hurt. I'm gonna try not to think about it too much because I think I might actually get jealous. And I used to think I had a vivid imagination....
