In a way that allows for forgiveness or is excusable.

Remissibly → It is formed from "remiss" (from Latin "remissus", meaning relaxed or negligent) and "-ly" (a suffix meaning in a manner). The word "remissibly" means in a manner that is negligent or relaxed.
Think of being 'relaxed' or 'negligent' ('remiss') and how the '-ly' suffix indicates the manner of that action.
