Paraphrase Julius Caesar?

We have to kill Caesar. It's not personal; we have to kill him for the good of the country. He wants to be emperor, and being in power might change him. If we let him be emperor, he will have power to harm us at will. Ambition is dangerous. Even though Caesar is a nice guy right now, history shows that once people have achieved supreme power, they begin to scorn all those below him. And in order to justify our actions, we will have to explain that we are killing him in order to prevent him from becoming a bad person.
