Death Penalty

I wonder if the Indian Government can be charged under IPC Section 302 for ‘legally’ killing convicted criminals?? When the constitution guarantees right to life… how does it give the judges to take away the same right? I am in no way justifying the crime committed by the inmates. Every person violating someone else’s human rights should be punished and punished severely… but killing them because they killed someone? It is then “murder for murder” and an eye for an eye… Like Gandhi says... “An eye for an eye will make the whole world blind” I am sure if this is the rate India is progressing in awarding death penalty then the whole system will turn blind very soon.
