There is simply no comparison between a man who is armed and one who is not. It is simply unreasonable to expect that an armed man should obey one who is unarmed, or that an unarmed man should remain safe and secure when his servants are armed.
A man who wishes to make a profession of goodness in everything must necessarily come to grief among so many who are not good.

And of all princes, it is impossible for a new prince to escape the name of cruel, new states being always full of dangers.
