There were two questions on the original posting and I would answer both.

1. A dead politician is the best kind of politician. S/He cannot screw up the country any longer.

2. As far as the best leader for Nepal, I think it would be Deuba. He has some vision and he has some good advisors. Now, whether he or anyone else will be able to lead the country out of the current mess is totally different question. There are too many variables outside of this person's control.
