India should:
1. Not pass knee-jerk laws, it takes a long time to undo the damage.
2. Do away with the death penalty.
Mobs of 'concerned citizens' always turn into sadistic assholes when they know their anger is righteous. But once the punishment of death is off the table, there would be one less way to cause serious damage.
You should see how the discourse in India has become, with good people suggesting more and more creative ways of torturing the rapists; disembowelment, chemical castration, and reversed re-enactment of the original rape have all been suggested.
A national exercise in revenge is sickening. Good, kind people braying for blood is sickening.
