A few choice words id say.

[Drich]

That's my point. Their isn't free will. That is a greek construct and not a biblical doctrine.
We are slaves, as such we have been given one singular choice. (one choice fee will is not.) That choice is to either to continue to be a slave to sin, or to Serve/slave to God. Before we had no choice but to serve/Slave to sin.

It's your God that determined all of mankind would be slaves to a sinful nature after the original sin occurred, isn't it?

ah.. no.

The doctrine of 'original sin' is flawed critically.

nothing in the bible spells out this doctrine.

The 'Original Sin' did not happen between Man and God. If it was, then where did the 'serpent' come from?

The Sin that A&E Commited was to eat from the tree of the Knoweledge of Good and Evil. If anything this knowledge in of itself is not sin, it just makes one responsible for the sin they commit.

This means, you like everyone else experienced their own water shed/eat the forbidden fruit moment, once we realized what we were doing was wrong, and yet did it anyway.

That is send us to Hell, Not what someone else did.
