They said other similar cases should also get attention and demanded effective and efficient policing so that criminals do not get away with such crimes.
"This was a heinous crime, but it is not the time for celebrations but for sober reflections. It's time to remember Nirbhaya and many other Nirbhayas in the country who are yet to get justice," Kavita Krishnan, Secretary of All India Progressive Women's Association, said.
She said death penalty is not a deterrent to rapes.
Supporting her views, Kalpana Vishwanathan of NGO Jagori said surveys conducted abroad have shown that capital punishment does not work as a deterrent in rape cases.
"...Better policing, change in mindset, swiftness and surety of punishment and ending impunity will help as deterrent in crime against women," she said, adding that it is good that the December 16 gangrape case reached its conclusion and the convicts were sentenced quickly.
Nisha Agarwal of Oxfam India said the need of the hour is deep "attitudinal and behavioural shifts" which enables women to live a violence-free life. "We hope that all cases of violence against women are dealt with in a fast-track manner."
Former IPS official Kiran Bedi said she was "relieved to see beast sent to hell."
