are you implying that Tor is not used for illegal or immoral purposes? (I took out the primarily that you threw in to make your argument stronger because that made my argument stronger, and I took out your scare quotes because morality doesn't scare me)

this is a helpful answer, downvoting it would be extremely bad form
I have no idea who is using Tor other than that I heard it can be used by people requiring privacy from governments, e.g. whistleblowers. It also seems to have broad support from the tech industry so I'd be surprised if it was in fact primarily used for illegal or "immoral" purposes. That's why I'm asking.
What's a scare quote?
