You do not carry yourself like any 20 year olds I know. Artificial and otherwise. My oldest brother is like your age.
Both- to my belief and my actions. I have killed humans for such things. For other reasons as well, but most people are liars anyway.

[he grimaces a little. He really doesn't get too involved with his siblings' affairs. While he is perfectly capable of the sort of dismembering they engage in, it does not interest him as much.]
