criminals are not always bad people: https://www.youtube.com/watch?v=VrFs2_uhz-o

and to break it down lawfully or/and morally bad:

  lawfully bad, morally bad = bad and crypto is one of the major tools in your arsenal

  lawfully bad, morally good = neutral, but you are a prosecuted criminal, crypto is helpful for you but there are alternatives

  lawfully good, morally bad = bad, but not a prosecuted criminal, crypto is not that useful for you

  lawfully good, morally good = you are not a criminal, crypto is not that useful for you

Laws at least have the advantage of being written down. Morals are different for everyone and not constant in time even in a single individual.
