Sociopathic Ninja

He doesn't conform to the norms set by the society. He is blunt, does whatever he wants, and cares little about his surroundings. He values little of emotions. He uses people instead of befriending them. People call him by many names. The last addition to those names is misogynist. With so many people against him just because he perceives the world as it is, how will he live in the world where being realistic is a must and feelings matter the least? Will he feel his previous world better or will he feel at home? Whichever it is, he has to spill a lot of blood.
