Doctrine to address or alleviate someone's sense of betrayal?

Does Buddhism say anything about suffering as the result of having a sense of "betrayal" -- perhaps a sense of someone else having committed an "injustice"? I think that for some individuals it's an important and a very long-lasting type of suffering -- for example: - if they feel betrayed or mistreated by their parents - ... or their spouse, their children - ... or even become outraged as a result of criminal offence by a stranger - ... or even just impersonal bad luck ("oh, that is so unfair!") But although it can be important, I see [nothing about it](https://accesstoinsight.org/search_results.html?q=betrayal) on Access to Insight. The one possible mention of it that I can think of is Dhp 3: > "He abused me, he struck me, he overpowered me, he robbed me." Those who harbor such thoughts do not still their hatred. Another mention in passing might be the parable of the saw -- i.e. the importance of keeping a mind of good will even if you are abused -- but that's all: very few examples/mentions. I understand it as being a specific case of a more general problem, i.e. of "craving" (for things to be other than as they are), and "I-making" -- but **do you know any doctrine on this more specific subject, i.e. of betrayal and/or a sense of injustice?** Also is it right to say that Buddhist doctrine on the subject tends to "well actually, you deserved this misfortune" -- for example something like [the origin story for Dhp 5](https://www.tipitaka.net/tipitaka/dhp/verseload.php?verse=005) implies that if someone persecutes you, then perhaps that's a result of something you did in a previous life. If so, **is there a way to paraphrase or explain that principle to a modern non-Buddhist audience?** Because "actually it's your fault" might be quite unwelcome (therefore ineffective), the modern view tends to denounce that as "blaming the victim", and the victim themselves might want to know that you're on their side and not siding with their abuser. If this is a 'reference request' question, it might be asking for doctrine from outside the suttas.
