Yes. All rapists should be put to death. Rapist cannot be rehabilitated into society and the Delhi gang rapists not only raped but they also murdered their victim. I cannot think of a more fitting punishment than death for them, and I hope the people of India agree with me.
The Delhi gang rapists should not receive the death penalty. While his crimes may be dishonorable and severe, they do not justify the death penalty. He would be better served by spending time in prison, where he will only receive the worst that life has to offer. He my as well suffer, just like his victims have suffered.
