While there was a lot of what seemed like chaos happening during Season 1, a lot of things that happened did end up being orchestrated.
That massacre flashback with Teddy seemed out of character and uncontrolled, but in the finale we learned it was orchestrated by Arnold and played out by Teddy and Dolores.
Speaking in a set of shots that HBO cut together as part of a clip that aired following the finale, Jonathan Nolan noted that Season 2 will be all about chaos.
Control of the androids, control of Westworld and more were key in Season 1, but by the end of the 10 episodes, that was all devolving and real humans were being murdered on property en masse.
