Earlier quoted context omitted.
I haven't read anything that suggests that Steve was cruel or a jerk for the sake of it.
He told Wozniak that they had made $500 on a sale but in reality it was 5000 and he kept the rest. He refused to recognize his daughter for along time. He refused to give stock options to a lot of very early employees. Wozniak then made a up for it. He was a jerk. Especially the story about his daughter is plain evil. At some point you have to take responsibility for your actions.
