Everyone will realize their mistakes, sooner or later, and fix their behavior going forward. The forward direction is important because it can be its own mistake to make amends to the past and the people you met, since they are no longer where you left them. What counts is the future and the people you will meet, because that's where the universe awaits. So the question that remains is how quickly each turnabout comes. Will the realization to correct take minutes, hours, days, months, years, lifetimes? Is the awareness coming faster or slower each time? The more you stretch it out, the more risk of dangerous reaction from others as your own outward behavior worsens. The realistic goal is not to make all regrettable impulse disappear, but to increasingly arrive at regret before taking irreversible action. The wise one will reconsider within, to offer up their best to the outer world in the time allowed. There's no shame in closing the cycles of intolerance to acceptance privately, that's what the inner world is for. How much better to address the hateful thought today than the hateful action tomorrow. But if that is not possible, at least to have left the hateful thought to tomorrow rather than become committed to the hateful deed today.
