Djokovic is known to go into fits of rage, smash rackets dangerously close to people. hit balls ouside the court when he is mad, confront and insult members of the public, act like an entitled drama queen when he feels he doesn't get the public appreciation that he deserves (while engaging in cringe-worthy antics like the boob throw at the same time), defend controversial points of view, organize mass sporting events without minimal precautions while a pandemic is causing thousands of deaths in neighboring countries, etc. Not to mention his dad is a giant tool and a clown claiming that "God sent Novak".Everyone loss **** time from time, humans have emotions. However you see at these emotions its up to you. For you hitting ball hard with anger into ball boy is not as bad as accidentily hit lines women with much slower ball. Well ok its your opinion.
I like Novak for his tennis play and for his behaviour outside of competitive matches. And i never call someone psycho when i dont know his true personality.
What do you expect? Of course the guy is not Hitler or Pol Pot. But he is not Fedsl either.
