Some people wants to remain anonymous, and Monero is good for that kind of people.
But Monero can be also used by bad people who want to hide their identity, but this doesn't mean Monero is bad.
All is back to the people who use Monero and their intention, good or bad.
we cannot judge a project by such uses. the use of the platform certainly has a well-planned goal. but when there are people who have bad goals, of course, it will have nothing to do with the project. If they want to stick with market confidence, of course, the ones made for the market are the best. therefore, there is system maintenance and improvement which is carried out periodically.
