Everyone is under the influence of power. Most of your behavior is shaped by the power organizations and individuals have over your life. Your value judgements are shaped by them. For instance, being a useful employee, a good student, even a good spouse is defined by the people who have the power to judge, reward or punish your behavior. To want power is to go against this current and push your own values.
The why of power isn't as relevant as the how. Historically every powerful person has had a "purpose". To give some moral underpinning is a shallow veneer that excuses the actions necessary for power, since power is a full time job. If you have power then that is your purpose, since anything else would keep you from it.
Look too closely at any powerful person with a purpose and things get ugly. Whether it's FDR, Bill Gates or Walt Disney. Power comes first or not at all.
