yes
He treated his brothers and father harshly but he did so for the cause of islam. Havent you heard the war of Aurangzeb with his brothers was actually a war of ideologies (this question have been included in previous papers)
his elder brother who was half hindu wanted him out of the throne thats why he waged war against him. As for as his father is concerned,the king remained puppet in the hands of elder son thats why Aurangzeb,in his presence, ascended the throne.
And Aurangzeb never started war with any of the his brothers. His brothers preceded in waging war and to maintain the empire he had to come out in field for war.
As aurangzeb was true follower of Islam thats why many contemporary non-muslims drew grim picture of his reign.
