I agree on your last statement. Apophatic inquiry is more powerful, and demonstrates the power of the negative, which I have posted about before:

Shatter, Destroy and Stop the Falsity

One drop of evil, one falsity, will ruin the integrity of an argument or anything else. Logic is fun. To resolve the issue of falsity, immorality or evil, indeed, a removal of that polarity must take place, not an addition of the other polarity to attempt to "even" it out. This doesn't demonstrate one is more real than the other due to this aspect of how one is created compared to the other or how one is removed compared to other. They don't have to operate in an identical fashion to validate the existence or non existence of one relative to the other.
