"The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants."
John Adams:
"Remember, democracy never lasts long. It soon wastes, exhausts, and murders itself. There never was a democracy yet that did not commit suicide."
And on, and on, and on.
The choice to make the US a republic rather than a democracy was carefully considered and hardly accidental. A good part of our Constitution is meant to protect us from the evils of centralized government.
Cheers,
