An old story with the highest ideal of Hinduism is presented.
A sage, seated beside the Ganges, notices a scorpion that has fallen into the water. He reaches down and rescues it, only to be stung. Some time later he looks down and sees the scorpion thrashing about in the water again. Once more he reaches down to rescue it, and once more he is stung. A bystander, observing all this, exclaims, “Holy one, why do you keep doing that? Don’t you see that the wretched creature will only sting you in return?” “Of course,” the sage replied. “It is the dharma of a scorpion to sting. But it is the dharma of a human being to save.”
Compare this with ‘one can kill a cow if it tries to kill you’.
