Being a sinner just for being born

[dyresand]

So your position is we inherit a sin nature, which isn't our fault. But we sin because we have free will, and not because we have a sin nature?

I think the fallen state makes sinning highly probable. However, at the same time, I think that free will guarantees it (with or without sin nature).

But overall were more moral these days were not killing each other for various reasons for the most part. 
And in general the world is a much better place now than 50 to 60 years ago.
