Mental Note: Taking over the World

Lets imagine for a moment that a person is actually trying to take over the world. I have to ask: if they are doing it for a good purpose, why should we stop them? I mean, if hypothetically I wanted to take over the world, get rid of debt for various nations and enact a world currency, would that be so wrong? Now, not to be confused with people who want to take over the world for all the wrong reasons like material gains and whatnot. If a person wants to take over the world and help it at the same time, I believe they should be given a chance; because sometimes thats all a person needs to succeed.
