Sylux, "Might Makes Right" is something I only believe in two different ways, one of them unconventional.
1) Whoever holds power determines what is seen as 'right' and 'wrong' by the masses.
2) Only they who hold power have the capacity to 'make right' - to change the world for the better. (This was the basis of medieval codes of chivalry. You know, the ones behind the modern idea of paladins...) I value empathy in an odd way; I feel it's the duty of the strong to protect the weak.
I probably don't believe it in the sense you do, which is "Might justifies any action." I used to; now I don't.
