Everyone wants power.
Unfortunately, power is treated and viewed as a limited resource. To have it means that a lot of other people do not have it. To have power, after all, means that a certain number of people (willingly or not, knowingly or not) have to submit to your will.
To have none makes you vulnerable to those unscrupulous enough to use you on their way to more power or just those sadistic enough to want you to suffer. But ironically enough, having power just makes you an even bigger target to those who would want to claim your power for their own. Not to mention the age-old and well-used saying that “power corrupts.” In other words, there’s a big chance you end up wanting more power to protect whatever power you already have to the point that you will cross lines and trample lines to get more.
