Are they really really really gonna do that..?
Even in a dysfunctional society with so much risks involved, and having been brought to by a very dangerous pandemic.
No one would be as insane nor sadistic enough to unleash havoc on one of the only peaceful things on a world in a state of disarray.
It's just all too convenient to have some chaotic evil character in this situation, there's not even any hatred aside from discontent in society, being a mentally deranged sociopath with seemingly similarly edgy mentally deranged friends and being in a to-do-before-death-list.
So far everything else was moderately realistic and comedic enough.
The boss, although such an asshole of a character, was able to actually function as a member of society, a lawful evil at the very least.
Now they're pushing boundaries, also very convenient that in this sort of situation, not a single person is guarding the tunnel.. normally, it should be VERY important, even to the extent of being a NECESSITY to have a group of locals on-guard with that tunnel and plugging it in much more than it is to ensure a 100% isolation.
Would still read, but this would just bring down the entertainment of being one of the only few takes on something so chaotic into an interesting comedy with twists of what-do's in this sort of situation onto becoming walking dead or other generic zombie drama situation.
Tho, if they turn this around into some sort of revolution to generic evil into a comedic uptake to actual success of having a peaceful community and proceeding onto the journey to the 100 list, then I'll be very much delighted as a reader, even with the drama of the father turning out to be infected and would probably sacrifice himself for the better of the village. (sounds cliche to have one 'sacrifice' himself for a cause, but well, if you know you're gonna die, and that you're absolutely gonna die with no return; then it'll feel much better dying doing something even the least bit helpful rather than being a complete utter asshole because of your hatred of any social interaction in the world)
