"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"

This quote by Dennis Potter suggests that bad deeds have consequences and can have an enduring impact. He suggests that bad acts can have a ripple effect, developing more bad deeds in their wake. Potter also recommends that bad deeds can be innovative in their own way, simply as good deeds can be. He uses the metaphor of yeast to illustrate this point, suggesting that bad deeds can act as a driver for additional bad deeds, simply as yeast can trigger dough to increase. Potter's quote functions as a reminder that bad deeds can have significant consequences and that we should be mindful of our actions. Eventually, Potter's quote motivates us to hesitate prior to we act, as our actions can have a lasting effect.
