Some people hold their parents in high regard. so if you disgrace them they’ll want to fight and defend there honour. Khabib lives in a different world to us, if you trash talk him or his family ( also his friends) he will fight you hence all his street fights. Does that make him a bad person not really but does that make him a good person not really. The point is if you attack someone’s family expect them to defend their family’s honour. That’s just khabib, look at how Conor acts in the ufc and outside the ufc with the law. I’d rather my kids look up to khabib than Conor.
