I get the disease but I survive, because I am amazing. (I also stole your antidote as a backup. NO LOOP HOLE THERE. And yes, it was the real one.)
My guinea pigs also all survive. I replicate it and store it in my impossible to find safehouse. Then I give you a disease that eats your stomach lining out and kills you. No cure that you know of (Or anybody else except me MWAHAHAHAHAHAHHAHAHAHA)
then I watch your slow agonizing death as stomach acid leaks through your body. I throw the carcass into the sun. My hill.
