Sick? Maybe... that depends on your definition of sick. Nothing SERIOUS will happen, but maybe a little diarrhea or an upset stomach (think drinking a shot of vinegar for the upset stomach part.)
Death? No. There are no deadly pathogens that can live in beer, so you will not die from a spoiled batch.
Your biggest problem will be that it will taste terrible.... so terrible that you will probably not want to drink enough of it to even make you sick.
