The long and short of it is this... if you'd been expending your energy/votes on encouraging good works instead of punishing bad ones, you'd have had a much greater impact... though it would likely satisfy your ego less. Man loves power, and nothing encourages man more than the exercise of his power to lord over others. It's much easier to feel good and "just" for punishing those you deem a villain than it is to take the same power and slowly attempt to raise up those less fortunate, often thanklessly.
