I pity the man who robbed the drug addict. It is very disturbing indeed. How could someone behaved in this manner and it happened in Stockholm, supposed to be one of the safest city in the world. I can't imagine how much negative karma has this man triggered by leaving an unconscious person lying on the rail track. But i can't help to think that did the unconscious man himself had so much negative karma until it triggered him to die in such a horrible manner? Or does this two person had something to do with each other in their past lives which resulted this to happen in this life?
