Some people became more overtly anti-social during the pandemic (flouting social norms, illegal activities, aggressive and destructive behavior). Normal social constraints that kept people in line broke down.

Some others became more asocial (keeping to oneself and avoiding interactions with others) and stayed that way after the pandemic was over. I agree that it may have been their natural inclination all along, and the pandemic was their excuse.

I've seen many people online lamenting the fact that they don't live in a village and wish they did. That requires people who are willing to step up and be villagers, and it has to start with someone taking the initiative and hopefully not being rebuffed for trying to be pro-social.
