Hm, tough call. For me, it would definitely depend on who the family member was. All in all, a zombie is a zombie and once a victim turns it's you or them... rock'n'roll, indeed!
I know it's cold hearted, but survival is key. I wouldn't kill them until they changed unless they begged me to, even then it would be hard to do.
The real question, the one that will be the most difficult, if you're with your family and a situation occurs, do you fight to the death with them and make sure they all make it out, with the possibility of dying, or do you lose the baggage and go your own way in order to survive?
yes children and women first heehaw
when it comes down to it i would kill whatever animal humans zombies it's all the same in world war z........
animals for food and maybe if they have been feasting on infected flesh
Survival of the fittest. That's what it comes down to. Take the weak and small ones first. Take out grandpa because he's close to death anyways, but then he'll taste more like jerky I would think. Human jerky.
