Yeah it's fun to goof around of course ;)
Anyway if it's a slaughter-house we want... why not do a proper battle royale next time? Go back to the old rules with multiple moves, let people start with nothing and let people search/run across the map to find weapons to kill eachother with.
And on top of it, each player who dies will resurrect as a zombie one or two turns later to add more chaos and mayhem.
Sounds like it should be fun. I'm all for it if the majority of players like the idea.
