Maybe, but that's not what Harry Potter Wiki or Wonderbook stated (AFAIK regarding the latter source). It said any dark wizard or witch who performs the Patronus Charm WILL end up being devoured by maggots, and even showed a picture of one such wizard suffering that fate, Raczidian, and there's little indication as to whether he knew full well he was evil or believed himself to be good.
