One Piece - A Devastating World

This world is plain rotten. People are terrible, they're cruel, they're fake, they always pretend to be something their not. They're weak. They take advantage. A cruddy little man who sees God in a snake and the devil in thunder, will take you, prisoner, if he gets the drop on you. Give anyone half a chance and they'll make you a slave; he'll tell you the most awful lies. I've seen them, running around playing innocent and righteous. Just to take advantage of you. To make it the worse the moment you've lost your usefulness they'll pierce a knife through your chest without batting an eye. ... Unempathetic,Inconsiderate,Greedy,Selfish MC. Male lead. No harem. Mc would 100% sacrifice babies or fetuses for power and does a lot of bad stuff for the right reason. Almost no romance, definitely not an idiot MC. I myself enjoy villain protagonist. I don't mind romance so long as the girl is just as messed up or evil and not given too much focus. I probably wouldn't even mind normal protagonists that are treated as being evil due to being locked into morally gray choices. It still gives me the feeling of following an atrocious villain of the story which I enjoy and who knows maybe you would as well. So just give it a try...
