This attitude works well in social situations where you have some advantage (parent, boss) or are roughly on equal footing. It works less well in non-social settings (the natural disaster example other people are giving) or if you are at a serious disadvantage. For the example he starts with, where he was an embittered boss who felt screwed over, he is absolutely right: "Forgiving" others requires you to first blame them. Blaming them when you had the power over them is petty and asinine. Embracing your own power is far healthier, more effective and feels tons better. And it leads to future outcomes where you stop and wonder what you could do differently to not set your people up for failure.

Though I think it is a tad unfortunate that some remarks here are taking it too literally when it was clearly intended as lighthearted and tongue-in-cheek.
