What type of person? Perhaps a Negan-type character, or Mad Max? How would your morality change, do you think, and what would be your new social roles?
This is actually a poser, despite all the book & movie tropes out there. It would to an extent on the actuality of the new "society", if there was one at all, & who I was responsible for. Otherwise the question is just way too open to honestly answer. for me, at least.
Every bit as conflict averse and armed as now. Maybe a facial tattoo, They rather expect that now, I think.... lol
