You don’t need a war to see how people really behave and who to trust - just have a death in the family and watch vulture relatives fight over the STUFF.
Now imagine how those same people would act in a true SHTF scenario...
Good point about the funeral vultures. Add the everyday two-faced ones and holier than thous to the list.
There is a sizable segment of the family I don't trust as far as I can throw them as a result of such observation. There are a couple who need not even come in my house.
Sad, but true.
