The 15th question is:

A STORY:

Once upon a time, there was an old crow who circled a tree full of mice, rats, squirrels, and chipmunks. The tree stood in the center of a corn field, so the old crow never had to eat any of the rodents, in fact, he was given the job of protecting the weaker rodents in the tree from those who wish to hurt them. One day, the smallest mouse in the tree was picking nuts, but three large rats approached him, took his nuts, and beat the small mouse. Later, the crow saw the injured mouse and asked him what happened, and the mouse told him about the three rats. The next day, the little mouse went out again to pick nuts, and ones again the three rats approached him to beat him up and steal his food. This time the old crow was flying around the tree, and when he saw the rats beating the mouse and steeling his nuts, he got angry, so he swooped down and picked them all off, one by one, taking them to his nest, and when he had them all in his nest he pecked their eyes out, broke their legs, and ate all three of them alive.

What is the moral of this story?
