Drew Karpyshyn started out as a designer of violent video games and, essentially, that's what he does in his books -- they are novelizations of video games rather than actual novels. They are to prose literature what rhymed birthday greetings on Hallmark cards are to poetry.
As to the three quotes you posted, I don't know if I'd go so far as to dignify them with the word "philosophy." They represent an expression of a kind of pseudo-Neitzschean nihilism which was (and probably still is) quite popular with the Skinheads of the last couple of decades of the 20th Century. Notice, there is absolutely no concern with anything resembling ethics; the whole 'philosophy' is about the Will to Power with all other considerations cast aside.
I don't know whether you'd be interested in living in that kind of world. I know I'd prefer a quick death.
