I understand what your saying about his scars adding depth to him. Don't think I don't want depth and complexity. I want them (the kids) to be just as well written and developed as Eric, Raven and Charles.
I love Kurt being a very religious person, but the idea of him having such strong faith in his religion to the point of marking his body everytime he "sins", adds him a layer that I particularly don't like. (considering, of course, it's the same motivation from X2).
I'm definitely not againt depth and complexity, if that's what you're implying. I just don't like this.
