Do you know what I find so dreary about the humanity switch? Same thing over and over. I don't need to feel, its so freeing. Thousand years and I've never bothered and you know why? Because I don't need to flip a switch to do the things I do.
So go on, bleat about the same things Kol did. But know that I am coming after you and I will find you. And we'll fix you, not because I'm particularly bothered about who you go and massacre or anything, its because I'm not dealing with centuries of self indulgant dramatics excused because of a little switch in your mind.
Even as an emotionless idiot you can work that one out.
