Indian Terrorist Sarabjit Singh attacked in jail by fellow prisoners

re: Indian Terrorist Sarabjit Singh attacked in jail by fellow prisoners

Why cant we compare him to kassab, both were criminals and terrorists, or am I missing something. Is this the first instance in the world of criminals turning on criminals in jail and killing them. If not, than all the places where such things have happened we must declare them uncivilised as well. Talk about gettign carried away.
