Inherited/Original Sin?

Inherited sin is a doctrine amongst many denominations of Christianity, yet the Bible explicitly teaches that sin is not inherited at all.

Psalm 139:13-14 - God created us in the womb. Did God insert sin into us during creation?

Deuteronomy 24:16 - We are not responsible for our Parents sin, "...each will die for their own sin". Here is an explicit verse that refutes the possibility of inheriting sin from Adam and Eve.

Ezekial 18:4 - Verse similar to the above verse "The one who sins is the one who will die."

Genesis 4:6-8 - Even though Cain doesn't listen.. God tell him that he is the ruler over his own sin.

Romans 5:12 - Looking at what Paul says in the New testament about it... Sin entered through man(doesn't say how or why?) If Adam sinned then sin was always possible with the "creation" of man. The inheritance spoken here is "DEATH" not sin itself. Death was the result of the first sin, so we inherited death from Adam and Eve, not sin. 1 Corinthians 15:21-22 goes on to support this.

Sin itself is a result of free will. Adam did not commit "Original sin". If you want to get technical it was Satan that committed the first sin by rejecting God and leaving Heaven with his angels.
