Or should he embrace the darkness that had always been his home, a place where morality was just another illusion?“Don’t box me in with your shallow ideas of good and evil,” he muttered, his voice calm but edged with danger. “I do what I want, when I want.”The air was thick with tension as he moved like a shadow through the dimly lit room.
