Marquis de Sade is oft quoted with derision (at least historic derision, I guess he is a hero now) in this context for he said there is no absolute right and wrong. Maximum pleasure for the maximum good. Kindness and love are perversions because they “restricted indulgence in pleasure”
Aleister Crowley “the wickedest man in the world / The Great Beast”
Anton Szander Lavey.. The founder of the Church of Satan. Believed that man should indulge in all carnal pleasures because this apparently is the nature of the beast.. This is simplifyng it, but that the gist of the beliefs.
