A total asshole never feels bad about their doings.
As such they are never, wrong-doings.
If you come out of a situation wondering what you did wrong, then you are automatically one step ahead of any competition. Self-reflection denotes an educated will which ponders on an end result and seeks to discover the ailment which led to behavioral malfunction.
If you are wondering, then you are not a total asshole and even if you have a piece of the blame for whatever happened, your logic is working towards rectification of self and soul.
The precise time and reason of wrong-doing are irrelevant. The moment of explosion, the "singularity", is an abstraction. Unless one habitually likes to berate and bemoan other people for their own pleasure or gain, then the moment of error is not of particular importance, unlike the underlying causes that led to it, and the way the aftermath is handled.
Optimal behavior dictates that "explosions" should be avoided, suppressed and generally eliminated. This is considered to be a higher evolutionary step. The will to transcend towards this new and improved state will usher your attempt closer to fruition. Until that state has been reached, careful pondering and re-adjustment is needed to minimize and/or eliminate such occurrences.
Resolution: Firm statements and demands, zero tolerance to inappropriate behavior from others on current and future occurrences. Self reflection - always, before, during and after. Dissolution of blame - the most important aspect of them all.
