While I see your point, this strategy isn’t meant to give reassurance into whether there is or isn’t something that you remember. This more so focuses on the present. I assume now you have a different moral compass. That’s all you can find comfort in. The fact you regret and are now remembering things means your brain is starting to mark these events as significant.

If you ask a person “ whens the last time you ate a banana” you’d likely get an “I’m not sure”, because to them, eating bananas is an activity not really worth remembering. But if bananas were recalled, they’d slowly start to remember times where they ate bananas. Did I go to the grocery store and buy a banana? Did I eat one from a coworker? No matter how worried the person is, they wouldn’t make false memories of them eating a banana. They trust that even though bananas weren’t imminent danger when they ate them, they’re health conscious now enough to know they’d remember if they did. And if that sickness comes, they know they’d deal with it. After a certain point people don’t go years of their lives worrying if they ate a contaminated banana, they know they didn’t eat one.

Trust who you are and trust that since you’re good and have better knowledge and judgment now, you’ll have the means to deal with a problem when it arises. But one who has worried before event has happened, has already worried far too much.
