No army can function in the world if it starts happening as you prescribe. Then every individual soldier would have his own judgements to rely upon and decide that if he is going to obey an order or not. What you are wishing for is called mutiny and keeping all variables and consequences in consideration, no senseable and patriot person can wish such a scenario.
What the establishment is doing or has been doing in this country is condemnable but the only way you can change it is through peaceful political struggle, and there is no quick fix to this as such struggles can take years. And be mindful of the fact that it is not about Gens. Bajwa, Asim Munir or Musharaf but it is a institutionalized sick thinking of absolute power.
