Fate of Rajiv assassins

The three mercy petitions of former Indian Prime minister Rajiv Gandhi killers was covered under the pillow of Indian govt for more than a decade.The authorities did not have a word on it for a long time due to political reasons.
And when the president takes a decision it is already late. The supreme court stays and advise the govt to consider releasing or diluting the punishment of  the convicts.
why it happened is because of the inaction of all the present and previous govt s.
Whether it is a soft corner on terrorism to release them is a question . But the govt should learn a lesson from it to take a correct decision at correct time .
