Allan, your premise is false. God does not "program" us with sin. We choose sin freely. The judgment for Adam's fall is that we all have a sin nature, of which C's and non-C's both agree, unless you hold to the Pelagian heresy. Romans 5:12 says that we have all sinned in Adam, which means that we all would have chosen the same as Adam. Otherwise, God would owe us our own personal Eden, and until we sin, we would get to stay there. But that's not the case, once Adam sinned, Eden was closed forever, because we all sin.
I'll admit, the Fall is mysterious in the sense of why would God (1) allow it and (2) allow the curse of the sin nature to affect all of Adam's kin? The tension is relieved somewhat by admitting that we all would have chosen the same as Adam. But then that begs the question as to why would God create an entire race that He knew would rebel againist Him? These are questions that both C's and non-C's must deal with. They are not easy for our finite minds, and if we are honest we must admit that we don't know God's hidden purposes.
Lastly, if you still want to hold onto your weak argument that C's make men out to be robots, then you must also deal with the fact that your theology also makes men out to be robots in heaven. God will "program" us in heaven so that we will not sin. Sounds like a robot to me.
