Simple. Second paragraph:
...they believed people are basically good, and I did not. I believe that we are born with tendencies toward both good and evil
Not good, not evil. Both. Neutral.
Or had you noticed that, and you'd quibble that it means conflicted, not neutral? I hope you wouldn't indulge in such hairsplitting. Equal pulls in opposite directions = neither one nor the other = neutral.
Either way, it isn't what either Testament teaches.
