Fable 2 Purity/Corruption?

I raised the prices on all my houses and shops to 100% but hen i lowered them all back to 0 it stayed all the way at corrupt and then i tried eating the food that gives purity still nothing so i tried lowering them under 0 by 1 to like 20/25 and still nothing and i don't know what to do cause i hate the horns.
Update: what if i beat the game and i own every house possible
