What's this - value relativism? (lol) If worth is subjective, then it's worthless. Marquis de Sade said it best, "What is, is right." (And we all know what this guy did, don't we?) That means, if all is subjective, then everyone and everything is right! Therefore, cruelty and non-cruelty are EQUAL. If worth is subjective then it's all in your feeble little atom-smashing brain - which, by the way, is also the result of random impersonal material processes. You also should write a letter to the U.N. - they believe in this thing called universal human rights - you should set them straight (you and Stalin)!
