Pakistanis have far more in common with the Afghans then India. Although the Afghans would be loathed to admit this.
India only helped Afghans to undermine Pakistan. That is one of the reasons why Pakistan and Afghanistan have always been tense neighbors.
In fact, India has been playing the same game as all others have been. The British, the Russians, the Americans etc etc. India can pretend its role is benign, and selfless, but its as self serving as any other.
Indians have it easy, they dont have live next to these people. While Pakistan has to absorb Millions of refugees and take in all kinds of guns and drugs and terrorism emanating from Afghanistan, Indians simply wait it out as others do the difficult work, and come in as soon as they see an opening like parasites to leach of the carcass of that decrepit state we call Afghanistan.
