[A.J.Armitage]

But it's not as if humans sin through some sort of automatic movement, like a robot. People choose sin, and choose to reject God, because that's what they want, which is why we're guilty, and why the lost will be damned.

Yes and no--I'd say that given our Fallen state, sin is in a fundamental way part of our being--i.e., the id.

People choose sin

I'm out of my depth, but let me see if I get it straight. God creates man with all of his faculties; those faculties are what resists the temptation to sin (or is it a unique Grace?); thus, God creates some men with the faculties that will resist sin and thus return to God, and some without...or do all have the ability to return, and some will not?
