So, I'm deathly afraid that the evil biomes will frick up my entire world when I enter hardmode. So, I've dug a bunch of hellevators and tunnels to contain the biomes and protect the jungle/my base, and probably spent at least a platinum on stacks of dynamite. However, I'm still worried that, by breaking altars, a stone block turns into evil in a protected space and nullifies all my hard work. Exactly how much of a threat to the world purity does breaking altars pose, and should I actually be worried?
