Answer:
Whatever is most effective is what is right
Explanation:
Niccolo Machiavelli was a man that is famous for his ideas. According to him, the people that rule should use the most effective methods to achieve the goal for greater good, even if that means killing of people, or leaving some people as sacrifice for the goals to be achieved. His views have been both seen very fondly by some, while some have been criticizing them a lot. During the period in which he lived and even after his death, his ideas were used by several rulers, and while they were cruel, they turned out to be very effective and fruitful, which just gives more credibility to Machiavelli's controversial ideas.
