You'd die in a zombie apocalypse. Everything you listed is messy, and you just infected yourself cause you wanted to use a messy weapon.

I find zombies one of the most terrifying thing. They are weak yes, but in a massive group you're screwed. It's an unrelenting creature that will not care if it breaks bones to get to you. And it can be your loved ones. Your loved one is contorting in ways you never thought possible to try to consume your very being. That's scary.

I can't figure out what's scarier than that that you'd want to turn around and go back towards the zombies.
