A mask can, no absolute guarantee, (a) protect the wearer from catching coronavirus, and (b) prevent the wearer from spreading coronavirus to other people. If you want to increase odds of you catching the virus, don't wear a mask. If you want to increase odds of you giving the virus to someone else, does that make you a monster in a Stephen King novel? A bio terrorist? Any different from someone with HIV not using a condom and/or not telling sex partners you have HIV?
