Criminals are prosecuted based on the crimes they committed, not for simply existing. If a criminal feeds hungry children but kills women at night, he would be prosecuted for murdering women; the act of feeding children won't be on trial, and neither will the act of feeding children be looked at as a bad thing.
It is the act that they committed that they will be prosecuted for.
So if the person who created Bitcoin turns out to be a serial killer or child trafficker, he should be jailed or killed for the crime he committed, not for creating Bitcoin.
We have had a similar conversation like this here before, and I mention few people who were awful human beings but made impactful inventions that made the lives in those fields easier.
If today, Satoshi's identity gets revealed, and later it is discovered that he committed a crime, I would personally campaign for him to face the penalty for the crime he committed, but that doesn't mean I can't use his invention.
You have noticed perfectly well that even if the creator is a villain, his invention will always be depersonalized, since the usefulness and value of the invention always have an advantage. As an example of the invention of a small but necessary thing by a person in prison, that is, a criminal, was a toothbrush.

. Society remembers only usefulness but forgets the creator. Time erases a lot, so whoever Satoshi was in his life (we all want to think only good things), his creation exists despite the history of the past, and moreover, no matter what.
