How do you think: does crypto make criminal life much easier? We all know that criminals use crypto to sell drugs, guns, people and everything else. Did crypto make doing such things easier? Earlier criminals had to think how to keep their anonymity and get paid, how launder their money, how to not get catched with this. But now they can just use crypto and all the headache about this financial troubles passed away. Of course there is much bigger positive points of crypto and not every user of crypto is a criminal, but anyway are you worried about this? Criminals also worsen the reputation of crypto that is not really stable itself.
Crypto currency is only a tool. They do not make anyone bad or good. People who are looking for ways to commit crimes will find them without cryptocurrency.
I totaly agree with what you said, as it is up to the individual whether they would use something to do good or bad things. And not just bad things but also in daily life as we could use money or even information against a person or use both of it for the greater good, it is just that we do not know the individual who does these thing unless they are already done.
