I'm expect my brother to jump start my car.
Why do you expect him to jump start your car?
Because he loves me.
I'm sure your brother will help you jump start your car because he loves you and wants to help you when he can. It's expected that people who care about each other do favors for each other when it's reasonable.
I don't do favors back. I like to make my brother's life harder and make him work for me.
It is not good to not want to do favors for your brother when he is so willing to help you. He might stop helping you if you don't help him when he is in need.
