I like the idea of some bugbears friendly to communities they live near them. However I think they would still be obsessed with the concept of fear and mostly solitary.
Basically imagine a bugbear coming down for festivals and acting as a Krampus figure, or going door to door threatening to eat naughty children if not offered wine and food.
(Note that friendly does not mean not mean not an enabler of probably bad parenting technigques. I’m basing this off real life traditions of people in costumes)
