Should I go into the family business?

My father has his own olive oil company. But I think it's just a cover up for what he really does. He never told me exactly but all I know is that he is good at scaring and intimidating men to get what he wants and making them offers. He has done "certain" things. Things that I do not approve of. But he wants me to run the family business. I have a brother, Fredo and another brother, Santino but everyone just calls him Sonny. Fredo was never seen as strong enough to take control of the business and Sonny was too irrational and temperamental. My father said that he has always seen good qualities in me. What should I do? Should I join the business to make my father proud or should I just stay out of it?
