“Good deeds never lose their merit, though mixed with some that are evil.”Miguel de Cervantes · Don Quijote · 1615 · Partea I, capitolul 22
One mistake never erases the merit of good deeds; moral life is a balance, not a single exam grade.
Cervantes rejects the idea that a single mistake wipes out all the good done before. Moral life is not an exam with one final grade, but a ledger where good deeds keep their value independently of the bad ones. The mechanism is fair judgment: to weigh a person only by his faults is as distorted as weighing him only by his merits. A doctor who saved hundreds of lives and erred once does not thereby become a bad man.
The card says good deeds keep their worth. The next step is about who does the weighing. Cervantes suggests that fair judgment requires looking at a whole life, not just the shameful moment. This is a call both for how we see others and how we see ourselves. When a friend lets you down once, memory instantly pushes all their kindnesses onto a dark shelf. An honest balance would keep them in the light, next to the mistake. This does not mean denying the hurt, but refusing to let it erase everything else. The question that follows is simple: why is it so hard to hold both sides in view at once?
Why it matters It helps with forgiveness — of others and of oneself — when guilt or shame threatens to erase everything good.
