fun_guy,

There is no "Head" of villian in Nepali politics.  No single person or even all of the names you've brought forward combined could have caused/is causing Nepal to be in its current state. These people are mere results of the "Khaobadi" system that has been been going on for ages. The "SYSTEM" is the main villian and "Corruption" is the medium. There is corruption everywhere, small offices, school, ministries, you name a place and it's infested with corrupt people.  Why is corruption so prevelant? The simple answer is the per capita income. Pople don't make enough money to be able to sustain normal life. How can a teacher making 10000 Rs per month survive in todays economy? If a teacher makes so less, imagine how much a gatekeeper makes. Inflation is at all time high but the salaries are from 1950's. So people have no choice but to be corrupted. And once you acquire a taste for making free money, there is no looking back. End results typically include 4-5 houses, 4-5 cars etc etc.

So blame the centuries old "SYETEM" if you want to. Even if you got rid of the people you've mentioned as candidate villians, the "SYSTEM" will replace them with people similar to them and the saga will continue. 

P.S. If you want to clean a gutter, you are going to have to step into it. Or if you are one of the wealthy/influential ones, you could try vacuuming it clean. Either way there is a price to pay. The question is are you ready to get dirty/see your bank balance decline??
