I' am personally of the view that whoever be the Criminal, the Capital Punishment should at any cost be abolished, instead, a rigorous imprisonment for life be slapped so that he/she can get a chance to repent on his/her past heinous acts of crime, in the rest of his/her life thus getting A CHANCE to do some good work for the sake of his/her Society or the nation, That's all my lord.
Here's one point, the captured DON is fully co-operating the legal authorities of our country so under the circumstances, he must be given a chance to survive by imposing the sections of rigorous imprisonment.
