Let us have a sense of proportion. Let us not fool ourselves and measure people by their actions and the results.
1. There were many many people that sacrificed much more for the country.
2. Your facts are wrong. Nehru spent ~9 years in jail. That too as a political prisoner with significant comforts, not the kaala paani kind faced by some other leaders.
3. Others spent more time. And incarceration never provided anyone the right to misrule foisting dynastic anti democratic politics et. al.
4. neru was an anti-Hindu (It is for nothing that Sardar patel called him in 1940s the only nationalist muslim in India). His contempt for Hinduism gets reflected in so many of his actions such as opposition to Somnath temple construction.
4. nehru's contempt for poor could be seen in the lavish and emperor like life style that he chose for himself, while mouthing empty socialist slogans. His totalitarian bent of mind took him to communist collectivist approachs.
nehru does not deserve to be named with the heros whose names you have cited - Patel, Rajaji, et. al.
neru remains the arch villain responsible for most of the ills plaguing India today.
