we c that 3 sons of amarnath n uttaraa r doin this to them its all bcoz when amarnath n uttara married they did it against his father wish it was their love marriage only mother supported and amarnath father passed b'coz of that shock after some time , now we see all his sons r givin them some kind of shock of love n marriages and devika did very bad to kakul so god need to punish her also.
I agree with you. If u do bad to others, bad will happen to you. AN and Uttra married without the agrrement of his father and now, all his sons and doing the same.
