Nuns and Priests: Defying God's Will?

I tend to think so.
Here is my reasoning: Instinct is humankind's connection to the natural world. The natural world is (supposedly) ruled by God. So instinct is basically humankind's connection to God. But so many followers of faith put aside their instincts as a way to prove their faith. Does this really prove their faith if they are going against what God instilled in them as human beings? For instance, the urge to reproduce a.k.a.  sex is something typically given up by those that become priests or nuns. Even the desire to eat is sacrifice by monks or other religious figures who fast.  So basically, in attempting to prove their faith, religious workers are actually going against the intent of their God. In more severe cases, religious figures act entirely outside of God's will, taking advantage of young children or taking large amounts of money and spending them on personal desires. This corruption of the church is unacceptable but expected based on the amount of power, but arguably equal to the corruption of ideals that the church has caused. Nothing should teach to work against our nature as human beings.
