Why the *beep*? *spoilers* but you shouldn't care

Why did Alex's father hide the formula in his adoptive son's shoulder, then tell him to use it when the time is right? What does that mean? When it's time to kill millions of people? It's a chemical weapon of mass destruction for Christ's sake! I thought the old man had become a moral man. This movie is terrible and I think it's a call to arms for Christians against Muslims, or everybody, or something. Absolutely, intellectually retarded, this movie.

Debt and debt and debt and debt and debt and then All will be enslaved.
