morality is subjective and people don't have free will

[SteveII]

Well, I call the immaterial mind that governs reason, freely chooses action, is the conscious command center of the body, is the enduring "I", and the thing that can be intentional about something the soul. I believe our soul is tainted by sin and we cannot do anything about that. Anyone who has had a 2 year old child can attest to the fact that we are born knowing how to sin.

I am not a Calvinist-- I think we have libertarian free will and God's foreknowledge is routed in his middle knowledge (molinism).

I am frankly nauseated by this doctrine.  As if a child learning how to behave (through often misbehaving) is sin.  

I sincerely hope you do not taint any little minds with this sick perversion that will instill in them an unnecessary self hate for the rest of their lives.  Ick.

Two-years-olds are absolutely willfully disobedient and do things to others that are intentionally wrong. You are confusing the child sinning with being held to account for those sins. I, and most Christians, do not hold a child morally responsible for their actions.
