No of course. I would't dare to eat an human because they still human that deserve to be alive.
It never stated that it would be someone that is alive, obviously that would not be very nice. I guess someone that recently died and the flesh is still warm. Or if you've had it in the freezer and slow cooked it to make it tender.
Either way, you sure that you'd never eat human flesh? Not even in a life/death situation? That seems a bit.. odd.
