[There is no concrete evidence he can bring against this idea, but there are a million niggling details that make him wonder. For example, the fact that Arcee told him that Megatron had supposedly poisoned the planet's core with dark energon - a bi product of the very entity Optimus Prime supposedly was trying to control.

Even if that accusation was a lie, why would the Autobots employ that manner of propaganda when their own leader was courting the same power? More than anything, one thing sticks out with particular importance.

He's been told so many times that he's not as different from Optimus Prime as one might think, and no matter his goals, and idea like that just seems unintuitive and reckless. Would even a more ruthless version of himself, one corrupted into being a tyrant to hold an established order, ever want the allegiance of the chaos bringer?]

It...It does not make any sense to me. How could a movement grown out of order and tyranny try to use a force such as Unicron himself?
