Can murder be justified?

It also says that the criminal had shot the activist twice to kill him, and he was chopped to death by the mob.

Though it has become frequent in our country, but isn't it unimaginable that people are actually being chopped to death? A few days ago a Dhaka University professor was subjected to such an attack. We have also heard about a businessman and his son being chopped into pieces. It actually took me a while to make myself believe that some ruthless people are really chopping fellow human beings with chapatti or such weapons, when I first heard something like that. But in this case, it is a criminal who has been chopped to death. Maybe for this reason it will be seen as 'right action' by some viewers. But does it really matter who or how bad the person was? The way he was murdered does leave a lot of question in our minds. Do you really have to chop someone into pieces to kill him? We, despite being the best living creatures in the universe, are committing such inhuman acts, and nothing is stopping us from doing such things.

Is there really no way to stop these acts? I would suggest that licenses be issued for keeping sharp weapons, and use of these things should be prohibited for general people other than butchers.
