I don't think the doctrine of original sin matters much one way or another. I used to get kind of offended by it, since why should I be held accountable for another person's sin? However, I have more than enough sin of my own; whether I have an extra amount of sin imparted on me or not makes no difference. There is no way I could live a perfect life even if I were born sinless, so it doesn't matter one way or the other whether I was.
It would if you died as a baby, before you were capable of being conscious of your need to repent and be saved. I guess it's that whole vague "age of accountability" question - can you sin before you're even old enough to have a clear concept of right and wrong? I don't think any of us would argue that babies sin - they don't have a freaking clue what they're doing. So whether you're born with someone else's sins as a blemish on you would appear to matter, in terms of the question of whether a baby who dies (or is aborted, whatever) would be saved or not.
Ironically, this gives a person who doesn't believe in Original Sin (or at least, doesn't believe it automatically makes
you sinful) an interesting pro-abortion argument. Kill an unborn baby before it has a chance to sin and it automatically goes to Heaven. OK, so that's not very funny, but I could see some wacko thinking that.
