Perspectives, point of views, or reports:
His report, her report, or their report.
Only Deities/Celestials know whom is right; the truth(s).
Humans seeking the truth? Have everyone involved in the issues together. Only speak of the truths and the truths shall prevail. Lies are exposed via legitimate/indisputable rationales by the truths.
To me, anyone starting the issues with malign intents first on purpose? After prior warnings? They’re at fault because they start the entire issue first. All the conflicts/repercussion of everything would be nonexistent without the person that started it first. Warning are already reminders to prevent issues and those warnings are actually forms of hidden forgiveness. Don’t be surprised of the unexpected change of behaviours/solutions after the third/second warnings/chances. Even the kindest person/soul has a limit. And that’s only healthy for anyone’s peace of mind.
