I agree. But depending on the Person and their upbringing of cause, the pondering can lead to a toxic self image, if this behaviour is internalized and seen as a charakter trait instead of a misshap. Thats i think due guild shifting into toxic shame.

So i think like you said the apology is helpful for the Person doing the apology to overcome a bad feeling before it turns ok them selves if they dont have a solid way to deal with emotions
