Tornado Cash is an anonymizer. Same as every cash drawer in every business. All kinds of money goes in - legitimate as well as illegitimate - and is mixed up together.
Does shuffling a bunch of currency notes together - some of which might be from a drug dealer - make you a criminal?
Being a money mule makes you complicit in fraud or financial crimes. Running cryptocurrency code and using your own cryptocurrency wallet to help launder stolen money is a crime.

Google "bitcoin financial oppression", and you'll find that cryptocurrencies are being advertised left and right as a tool to escape "financial oppression", or as someone less cynical would say, to evade financial regulations.
