Good deeds don't make news only the bad ones stick forever. He did commit some bad ones and his legacy would always carry these misdeeds.

While Aurangzeb was extending the empire in the east and south, and consolidating his position on the northwest marches, he was also concerned with the strengthening of Islam throughout the kingdom. His attempt to conduct the affairs of state according to traditional Islamic policy brought to the fore the problem that had confronted every ruler who had attempted to make Islam the guiding force: the position of the Hindu majority in relation to the government. In 1688, when he forbade music at the royal court and took other puritanical steps in conformity with strict injunctions of Muslim law, he affected both Hindus and Muslims. When jizya, abolished for nearly a century, was reimposed in 1679, it was the Hindus alone who suffered.
By now Aurangzeb had accepted the policy of regulating his government in accordance with strict Islamic law, and many orders implementing this policy were issued. A large number of taxes were abolished which had been levied in India for centuries but which were not authorized by Islamic law. Possibly it was the unfavorable effect of these remissions on the state exchequer which led to the exploration of other lawful sources of revenue. The fact that, according to the most responsible account, the reimposition of jizya was suggested by an officer of the finance department would seem to show that it was primarily a fiscal measure. The theologians, who were becoming dominant at the court, naturally endorsed the proposal, and Aurangzeb carried it out with his customary thoroughness.
Another measure which has caused adverse comment is the issue of orders at various stages regarding the destruction of Hindu temples. Originally these orders applied to a few specific cases—such as the temple at Mathura built by Abul Fazl's murderer, to which a railing had been added by Aurangzeb's rival, Dara Shukoh. More far-reaching is the claim that when it was reported to him that Hindus were teaching Muslims their "wicked science," Aurangzeb issued orders to all governors "ordering the destruction of temples and schools and totally prohibiting the teaching and infidel practices of the unbelievers." That such an order was actually given is doubtful; certainly it was never carried out with any thoroughness. However, it is incontestable that at a certain stage Aurangzeb tried to enforce strict Islamic law by ordering the destruction of newly built Hindu temples. Later, the procedure was adopted of closing down rather than destroying the newly built temples in Hindu localities. It is also true that very often the orders of destruction remained a dead letter, but Aurangzeb was too deeply committed to the ordering of his government according to Islamic law to omit its implementation in so significant a matter. The fact that a total ban on the construction of new temples was adopted only by later jurists, and was a departure from the earlier Muslim practice as laid down by Muhammad ibn Qasim in Sind, was no concern of the correct, conscientious, and legal-minded Aurangzeb.
As a part of general policy of ordering the affairs of the state in accordance with the views of the ulama, certain discriminatory orders against the Hindus were issued: for example, imposition of higher customs duties, 5 percent on the goods of the Hindus as against 2 percent on those of Muslims. These were generally in accordance with the practice of the times, but they marked a departure not only from the political philosophy governing Mughal government, but also from the policy followed hitherto by most Muslim rulers in India.
