Hatter
...that question is a bit harder. ...I don't think so. I think there is always a chance for someone to turn themselves around. To try and turn things right. But thing is, forgiveness and trust can't just be expected. That's something that has to be earned.
The ones from my world are, at least. Think of the strongest, most vicious, dangerous animal you can think of, make them super-intelligent, and add in the cruelest, most sadistic personality that a person could possibly have, and you've got a vampire from my world. Soulless monsters that find it entertaining to tear people apart and watch them writhe. People are nothing but chewtoys to them. Ones they like to break.
Katherine and Lexi aren't exactly like that. They are from a different world. Different breed. But that's what I see when I look at them.
...Not so much with Lexi now. She's just... she's so human at times, I can forget for a while. What she is. And she doesn't kill or hurt people. Fuck, she goes out of her way to get other vampires to do the same. But that nightmare image is still always in the back of my mind.
