I can respect his personal attributes, in that he was an observing Muslim and a kind man to those around him.
However, on a national scale, he deposed and hung an elected PM of Pakistan at the behest of foreign powers. He stoked the flames of jihad to get involved in Afghanistan so that he could rent out the Army. He destroyed the social fabric by his Hudood Ordnance which led to the Blasphemy laws. And when he outlived his utility, he was killed like the General-for-hire that he was.
Yes, he was a total disaster for Pakistan. Much of what is happening today is all his doing.
