The Prince

Good Idea:
These all seem to me like each idea is used to gain power through corruption but the best idea to me was that there should be no violence when taking over a country. Because everyone who helped take over for you could easily turn their back on you just like they did the last leader. I also believe that violence never solves anything so it's just an obvious choice to me.
Also using your resources and supporting the people who have supported you, agian, it's underhanded when you only help those, but I suppose it would work.

Bad Idea:
The worst idea was keeping the people in fear, even though it would work, it doesn't seem fair to just kill random people to keep in control.
