no. your human family members had souls, which we hope have gone to heaven or passed on to become one with the universe, or whatever it is they believed. hard as it may be, you have to be ready to spear dear old dad in the eye - as hard as you can - with a poker or whatever it is you can find when he reanimates. wherever he is, he'll forgive you for it.
A zombie has no memory of its former life, it will not be distracted by the family
pet or familiar surroundings. It doesnt matter who or what you were in life, that
person is gone, replaced by a machine programmed for only one function: murder.
You have to kill it because if you dont it could infect other survivors and it will
make one more zombie on your list. Regardless of who it was in your life that person is gone forever, you must kill it, zombies show no emotions why should you. sorry to make it sound so horrible but this is reality guys, sorry.
kill before you think, then when the shits all over, thats when you start thinking. hell, im in the military, i gotta keep the kill or be killed mentality. but if it comes down to it and i do that person in, when im alone at night ill probably think about it. you cant help thinking, its a human response. your going to feel remorse after blowing apart someone you knew, even if they told you to do it before they turned.
I know it is easy to say that they are no longer a family member, that they are no longer even a human being and I understand and feel the exact same way, but no matter how much I say I know it would be harder to do than anything else I have ever done in my life to put down an infected family member. Even if you know that all that made them who they were, that made you love them is gone, there is a difference between knowing and Knowing and I can't truly say whether or not I could do it until faced with having to.
