I don't know about "original sin," in the Xtian sense.

But uncorrupted is NOT the same as ( to use an overused term ) "virtuous."

Corruption implies taking someone or something to a worse state than you found it in. It says nothing about the state you found it in, only about the worsening of its condition through intervention.

Family anecdote.

As a baby, my brother used to be covered in tiny bite marks. ( In todays more "elightened" times, we would've been raised as wards of the State and my parents would be doing life sentences. )

It transpired thusly. Derek would crawl across the crib and ( not content with his own stuffed toy ) would try to take little Dante's toy too. Little Dante would put up no resistance. ( Gee, I suppose those allegations about Pedo wimpyness ARE true. ;p ) Eventually little Dante would smolder, and crawl back to bite the other baby in revenge. Finally our mother realized that what we needed was a crib-toy for each tiny fist, no matter how acquisitive. ( Note: Derek grew up to be a Progressive and Dante to be an Anarcho-Capitalist. There may be a lesson here? )

Anywho, baby's are born kleptomaniacs. Teaching concepts like "theft" comes later.

You might "corrupt" a born klepto. But being uncorrupted doesn't mean that babies don't steal, bite, or hit.

A better term for "uncorrupted" might be "unadulterated." ;p
