Power is nothing more than a tool to achieve your goals, with enough of it you can move the damn mountains if you want. The problem with power is not that is corrupts, screw that. The problem with power is that it is a finite resource, and like all finite resources it is constantly contested. Do yourself a favor, my son, when you are king make sure that none of your brothers remain among the living. And burn the corpse, trust me, powerful enemies tend to rise again and again unless taken care of while they're still young.
