No animal is a born a maneater,it becomes one only when it is forced.For instance when it is too week to hunt another animal it finds man an easy prey,especially a defensless man.When there is no other prey around and only a man is available it has no other choice to satisfy it's hunger.Jim Corbett in one of his books mentioned an incident when on a narrow path he crossed a tiger but was careful not to look directly in its eyes and instead turned his face and passed by without being attacked.
On the contarary man is and has always been a animal eater .
