Is your judgment of people affected by your opinions of their partners/spouses/friends?

For example, if you are friends with someone and you just can not get along with their spouse, do you wonder about your friend and their own judgment…as in why are they with this person? or do you wonder what’s wrong with you?...people always say you shouldn’t judge others based on their friends or family but to a certain extent, these are the people they choose to hang around and if these people are people you do not respect after interacting with them, does it make you question the person that connects you to them? What if your friend also sees what’s wrong with their friends but remains friends because ‘well you know we’ve been friends for a while’ and you simply can’t be friends with those people anymore, does it affect your friendship with the original friend? I know you can always spend time with them on their own but the company they run with, does it matter? Think of the company you run with..you closest 5 friends/partners/family members…if they were taken into a room by another person and participated in a focus group, what would the impression the researcher get of them and would there be a reflection on you?
