I dont know whether the natural calamities are punishment from God, but one thing is whoever crosses his/her limit and do atrocities on others or commits crimes , how strong they may be now, ulitmately they are going to be punished by the Supreme God,either in this world or in the life hereafter.
So after our death God will ask about our deed whether they are good or bad and He is going to reward us like that.So its better to thing about ourself how we are and how our life after death is going to be than thinking about others whether they are good or bad.
So lets thing about ourself and as human being let help others expecting nothing from them.
