I chose no for a few reasons. I think evil is, in itself, a human label. I don't think that there is anything that is objectively evil, and we are simply what we are. The things that we do that can be labelled as "evil" are only "evil" because of how we've come to define the word.

Also, humans are simply byproducts of their environments. A person that is born into a (subjectively) "good" environment is most likely to be a "good" person - to the point were even the thought of doing anything evil is so far beyond the person's scope of reasoning as to render the act itself impossible, without the proper motivation (which is, again, a factor of his/her environment).

I don't think we are born either way.
