Why don't we lose sleep?

Tavleen Singh In Indian Express makes an interesting point Why didn't PM lose sleep over 7/11?
The fact of the matter is that we Indian simply cannot overcome our lust for petty gains over longer term good. Its a story repeated time after time. Any outrageous act (not just terrorism, it can be local rivalry, political point scoring, regionalism in cricket team selection of all things, and its the same story.
The PM otherwise an honest man from what i gather hastily gives a clean chit to a minister who is forced to resign after a couple of days on the same issue and is blamed by the ruling party as guilty! Why was the PM not sacked for giving a "clean chit" without checking on facts? He is after all the Prime Minister. Or are we saying that the PM of India actually make statements he expected to be taken seriously without checking on facts? If not so then obviously he makes statements while knowing that he is being at best economical with truth?
The ruling coalition's Presidential nominee is accused of political and moral crimes and the spokesman says all political folks have these kinds of charges including the opposition candidate. How does the unsuitability of opposite candidate makes the choice of someone with serious credential issues right? Let both be declared unsuitable. Reminds me of that argument in movies where a criminal caught for an act says first catch all those who get away before catching me. What makes this so sad is that audience will happily clap if this criminal in the movie is a favorite star. We condone turpitude if it comes from our favorite people.
Somewhere I think we are ourselves to be blamed because we within our democracy refuse to punish leaders for their sins. Until that starts happening expecting those wielding power to be holy in thoughts is naiveté of tallest order.
