Living a double life. What to do?

My earliest memory is of me in a bloody dock crate with my mother laying bloody on the floor. I was then adopted and raised by a cop, his wife, and my sister Deb. Growing up, I had no emotions. To this day, I am completely empty. The only urges I used to get were to murder animals. My father had noticed this and began to teach me how to imilate into society. He also taught me something else. He taught me how to kill bad people. (Rapists, Murderers, Thieves) Now I am living a double life. By day I am a blood splatter specialist with Miami Metro and by night, I am a Vigilante. What should I do because I don't want my wife Rita to find out.
