Love?

I feel love for my friends.
I would kill for them.
I feel love for... him.
I would kill for him.
I do not feel love for my mom.
I would kill her.
I do not feel love for myself.

What is love? Not being able to live without? But how can that be true? The devil is the opposite of God for if there is to be as much good as God is supposed to be then it must balance out. Then If we use this theory God cannot live without the Devil. So God loves him. That makes fucking perfect sense.
