Hehehe,

Your father died 4 years ago, your mother went into an alcohol frenzy after that, that lasted 2 years. In that period she had a couple of boyfriends, one-night stands etc. She gets of the alcohol and keeps her last boyfriend. The boyfriend is 20 years younger and is mentally ill. The mental illnes is not improving. He attcked your sister multiple times. The boyfriend doesn't work and keeps you of your favorite TV show. Your mother wishes to keep the boyfriend. You are best friends with his brother who is a big-time underworld figure. He says that you may dispose of his brother if you really want to. Your mother would be defasted if you do, but she would be better of after it.

What do you do?
