I won't say Karan is women beater/abuser
But I do feel he has the mentality that women take advantage of men ,he is a person who thinks he is representing sataye hue mard Zaat
He has a streak of misogyny as in within a neutral situation (none of the party related to him or romantically inclination ) he will take side of a man over woman
Regarding this matter I don't think bb is trying to protect karan because they easily could have cut out entire scenario
