"Power tends to corrupt, and absolute power corrupts absolutely. Great men are almost always bad men." - John Dalberg-Acton Those who seek power also seek or will inevitably seek to control others. This is a fact. Power isn't as good as its made out to be. For every person in power that you hear great stories and lore, there are most likely a multitude of untold stories of misery and peril. "History is written by the victors." - Winston Churchill
You don't need to be in a position of power to do right by the world and make it a better place, and ultimately if that were the goal of everyone in this world, we could solve most of the worlds many problems, but you have to realize the world isn't a perfect place, and unfortunately not all people are saints. I applaud you for trying to make the world a better place in your own way. Remember, don't lose sight of you truly are. Always take time to reflect upon your origin and where you started. Are you still along that path?
