There are two aspects to your perception of a political leader.
- Criminal negligence
- Civil negligence
For #1, a court has to prove him so, otherwise he is innocent.
For #2, if you feel that leader X is not upto the mark, then DO NOT vote for him during the next election cycle.
If there are enough voters who feel just like you, then the leader X will not come back to power.
And the whole thing will done without creating instability, gali-galoch, and other matami methods.
That is what we all know as "civilized methods".
Unfortunately Western democracy is not out of the box solution for every country. Basic requirement for democracy to be successful is to have educated and knowledgeable voters and strict and quick justice we are lacking both in Pakistan.
People who think that democracy can work in Pakistan with whole villages/gooon voting on the orders of Zamedar/wadera...just live in fool's paradise.
Mixture of democracy and illiteracy (or lack of information) is unfortunately just like ganjey k nakhun. He does nothing but scratches his head.
