I actually do remember the concept of "Original Sin" and recall thinking how can I be a sinner when I didn't do anything bad. I recall the Nun telling us that without Baptism a child would be destined to purgatory and never admitted into the Heaven. I remember thinking, "how does she know" and "that ain't fair".
Both simple observations, but observations none the less which lead to my conversion to Agnosticism.
If I believed my sins might be expunged by a supreme being might I act differently? My answer is I would not; I suspect many who claim to be "Christian" do so because it's the "in" thing in many parts of our country and some because they believe "confession" and being "born again" expunges past evil deeds.
None of us can know what happens at death, if a soul actually exists, or if there is a heaven and a hell. What we can know is that the good we do while living lasts, as does the evil, in the hearts and minds of those left behind.
Catholics, in general, are the least likely to understand the concept of original sin. I often find that ironic when I consider that they also have no trouble telling me that I have an advantage over other people simply because my skin is a different color.
I do not like the term original sin, I think the term Adam's sin is more accurate. This did not make you a sinner, you manage to do that all by yourself. When Adam sinned he was cast out of the garden, and removed from the presence of God. He lost the ability to perceive the higher dimensions that is often called the spirit world.
As he was the father of mankind, we all also lost this ability. That is actually a rather simplistic explanation, because God actually cut us of from the higher dimensions. This is something he did as a consequence of Adam's sin, and we all reap from that harvest when we continue to sin. God is able to lift that barrier at any time, and has done so in some circumstances. (2 King 6:16)
I love the way you take what I say and twist it into something else. Your sins were not expunged by God, Adam's sin was paid for by Jesus. This action allows God to treat us as individuals, and not as a collective. If you look at Adam's sin as something that affected God, and not us, you might be able to understand that we are not guilty of anything just because someone else did something. That is why Jesus chose to die for sin, so that God would be free to reveal Himself to those that choose to look for Him.
I do not claim to know what is going to happen when I die, or when you die. The Catholic concept of Hell is not supported by Scripture, so I am not going to tell anyone they are headed for a place I do not believe exists. I am also pretty sure that heaven is not a place where God sits around on clouds and signs laws passed by an angelic Congress. I do not believe that Christians end up there when they die any more than I believe that Muslims end up in Hell.
By the way, souls do exist. Souls are us, and we all exist, until we stop breathing anyway.
Then the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul. (Gen 2:7 JPS)
