I am going to steal one BTC, and send every user in the world 0.00000001 BTC
Assuming you want to donate to 8 billion people, you will need to steal 434,400BTC as the minimum standard transaction is 0.0000543BTC.
Without transaction fees these still may take a while to confirm.
Also I am unsure how you will collect the receive addresses of everyone on Earth; you could troll the blockchain but that is only going to be people who already use bitcoin and you'll pay some of them multiple times.
I feel you haven't thought your plan through, but I look forward to my 0.0000543BTC with anticipation.
