"A bad act done will fester and create in its own way. It's not only goodness that creates. Bad things create. They have their own yeast"
About this Quote
The word “fester” is surgical and bodily, suggesting infection under a bandage: not melodramatic villainy, but a small wrong left untreated until it becomes systemic. Then he pivots to “create,” a verb usually reserved for art, love, and progress. That theft of a “positive” word is the point. Potter is telling you that harm is productive in the bleakest sense: it breeds rationalizations, complicities, cover stories, and the kind of emotional calluses that make the next bad act easier. He’s mapping how a single choice can reorganize a person.
“Yeast” lands as a domestic, almost cozy metaphor, which sharpens the sting. Yeast is ordinary; it’s what makes bread rise. By borrowing that image, Potter implies that corruption can feel like normal life: a quiet rising, a slow expansion you don’t notice until the loaf is already baked. That’s a signature Potter move, in keeping with his television dramas’ obsession with memory, guilt, and the way private damage metastasizes across years. The intent isn’t to moralize; it’s to warn that wrongdoing doesn’t just stain you, it starts making things - new versions of you, and new worlds around you - unless it’s confronted early.
