What kind of God would create such a condition in a boy, then damn that same boy for acting on that condition?"
I'd like to answer this, but I must point out that I do not consider myself a 'die-hard moralist Christian' ( at least as I think is beign implied in your post).
Yes, all these things are a part of being human. And I could not say whether or not God would condemn the boy to eternal damnation.
I cannot say that a premise implied in your argument is entirely correct--that because these things are placed there by God, they are an intrinsic part of our being, therefore it is completely natural and okay to act on every impulse that is generated by aforementioned characteristics.
After all, if a person is pre-disposed to alcoholism, most rational people do not run about encouraging said person to drink it up because that urge is entirely natural. In fact, they attempt to discourage the behavior and situations that would encourage the behavior because there are consequences.
People are given many instincts, that wonderfully contribute to the total package of being human. It is how these instincts are used and directed that is the question--and it is a philisophical question that cannot be answered in a concise form. The point about this that is being ignored, consciously or otherwise, by those who would be quick to condemn, is that the boy's motivation wasn't necessarily out of getting his rocks off.
Would I have tried to let the boy know that getting laid was not the focal point of human existence? Possibly. Would I set myself in the position of God and condemn the boy to eternal damnation for this? Absolutely not. I have no idea of what God would say to the kid, or what would happen. And I definitely would not be a Pharisee and quote Bible verses to justify a personal condemnation of the boy.
Your absolutely right! There is nothing wrong at all with sex and the desire for it.. In fact it's the best thing there probably is and it's what keeps the world going around.
But, there is a Godly way to it.. a way that world can never understand.
He did not create us in a junkyard dogs image, but His. It's sad this child had no other desire to look forward to before his eternal destiny was reached. It was not God who made this boy sick, That's not what His Word teaches and it's not His will that any of His creation go through such a tradgedy. You've been lied to.
