We were born without sin in the Garden of Eden. The notion of born with sin is simply a recognition that our souls were not fresh off the press when we were born. Sin literally just means error; and you couldn't argue a baby won't make mistakes.

The idea that one has to be cleansed when they are born is something I can’t agree with. All souls ARE fresh. Babies did not do anything wrong. They have no error, they do no error. You can’t hold them accountable for anything.
There is no accountability until one has been taught right from wrong, and had the chance to be given the a choice… then accountability starts.
I agree that babies are not born good or evil. I think much of this comes down to sentiment around what it means to sin.
This topic reminds me of the pre/trans fallacy that Ken Wilber has written about. Might be worth looking at if you're interested.
But the only way anyone could ever do wrong is if they were not properly taught right from wrong. The reason doing the right thing is right is because it produces the best results.
Evil is simply ignorance, and just like most toddlers are tyrants, babies are born ignorant.
