No, it's also the AI. There are two broad categories of horrible outcomes: 1. Bad people control and use AI to dominate/destroy the world 2. An AI is created which resists human control entirely, and it decides to take an action that doesn't bode well for us. It is a fundamentally inscrutable mind to us, so we don't know what action it will take or why.
