In the second case, when those who fight are of such a character that you have no anxiety as to who may conquer, so much the more is it greater prudence to be allied, because you assist at the destruction of one by the aid of another who, if he had been wise, would have saved him; and conquering, as it is impossible that he should not do with your assistance, he remains
at your discretion. And here it is to be noted that a prince ought to take care never to make an alliance with one more powerful than himself for the purposes of attacking others, unless necessity compels him, as is said above; because if he conquers you are at his discretion, and princes ought to avoid as much as possible being at the discretion of any one.
