I think it partially depends on what you are willing to forgive. For example, I am much more willing to forgive eagerness compared to carelessness or impatience. One thing to consider is that moving to a culture of "permissiveness" won't stop carelessness. In fact, it helps to embed it. People learn that they can offload being careful onto the one giving permission. Over time this leads to a worse situation since you end up having a lot of people who feel it is OK for them to be careless and you end up with one person (the one who can give permission) bearing the entire weight of carefulness for the entire org.
