They may, in Dying as Yourself, recover for just a few moments, but only if mortally wounded. Expect them to get Drunk on the Dark Side and suffer a Super-Power Meltdown because of it. Named villains and extras will usually give in to it much more quickly for the powers, and quickly betray humanity because of it.
Heroic Willpower is probably the reason for this temporary(?) emotional stabilization. If the hero or the villain catches it, they get Cursed with Awesome superpowers. This often works by an interesting rule: Mooks and Red Shirts tend to be turned into raving, mindless beasts/monsters. While seeking to cure himself, the infected hero must struggle with malign influence and limit use of the evil powers granted by the Corruption, since using them tends to corrupt him further. In the standard plotline, it will usually infect The Hero at some point. The Body Horror transformation progresses gradually, and the final result tends to be a hideous, slithering creature which looks like the spawn of an Eldritch Abomination, an Enemy to All Living Things capable of inflicting the Corruption on any creature falling into its tentacled clutches. The Corruption is a force of chaos that gives some of its victims a Superpowered Evil Side before (or while) it mutates them into mindless monsters.
