I Would Rather Die
There's a select number of people that come to mind at the term "loved one". Love doesn't come easy to a person like me but I'm lucky enough to have felt strong fondness and care to some people. People I would die for in a heartbeat, slight hesitation but no regrets.
So... Would I care if a thousand people stand risk of getting infected as long as I get to be with them? ...yes. I would. But does that mean I would pass up the chance and possibly lock my uninfected loved one out to die with my betrayal being the last thing they remember before experiencing an unreal amount of pain? No. I would honestly rather die than do that to a person I love, losing them when I had the chance to save them.
I'd like to think I could find a compromise. Everyone else moves to the back. Guns pointed at us on all sides. I open the door, they jump on me. To hug me or eat me I don't know. The moment there's a sign of danger, the moment we spot an injury of some sort that looks like an infection, they will die immediately. I'm not going to watch hundreds of people eat each other because I'm selfish and want to be with the person I love as much as I can. I'm pretty sure any the people I care about wouldn't want that, either.
So yeah. The chances are, if they are a zombie, they'd end up getting a bite in me immediately but that's okay. Because I got to see them anyway. It must have been so scary to be separated, I'd probably be relieved to at least look at their face before we both die. I'd let those with the guns know that if any of that happens, if the infection passes to me or whatever, we should both be killed immediately. I'd prepare myself for that. Headshot baby, safety first because I do not want the deaths/undeaths of a thousand innocent human beings on my conscience. I mean surviving a zombie apocalypse is enough stress, they don't need all that drama in addition heh.
