I guess it is realistic, if you consider exploding the whole world with nuclear weapons would mutate humanity into roving bands of psychopaths. I can see that happening. Nuclear and mutations and yada yada yada…

Yeah…

Or, or! If we all die, the lizid people can come out of their holes in safety. And those guys are for sure a bunch of psychopaths. I can see them making a Mad Max-esque world just out of fun. Like a huge theme park.
