Salieri an elder brother.

In the movie, Amadeus, a young Salieri makes a bargain with God.

I would offer up secretly the proudest prayer a boy could think of. "Lord, make me a great composer! Let me celebrate your glory through music - and be celebrated myself! Make me famous through the world, dear God! Make me immortal! After I die let people speak my name forever with love for what I wrote! In return I vow I will give you my Chasity, my industry, my deepest humility, every hour of my life. And I will help my fellow man all I can. Amen and amen.

What happens? Mozart comes along who has musical gifts far above Salieri. Then you hear Salieri who sounds a lot like the elder brother.

It was incomprehensible... Here I was denying all my natural lust in order to deserve God's gift and there was Mozart indulging his in all directions - even though engaged to be married - with no rebuke at all!

Salieri finally says to God, "From now on we are enemies, You and I." Unlike the father in the parable of Jesus God remains silent.
