It was originally going to follow both paths, but I found that there was already a wide variety and good amount of more "purity" choices in the main game, and the Corruption side was fairly weak and mostly just "Peter Bad" instead of actually delving into this idea that his desire for power and control might actually be harmful.
In any case, it's not that I don't want to rewrite the dialogues, but mostly that I've removed about 85% of the Purity paths altogether, and have zero interest in going back to put them all in again.
HOWEVER!
If you want to do that, I give you my blessings and a hearty "Good Luck!"
