Maybe the Titans behave similar to the zombies of the Resident Evil film series: The Titans do so only because of an instinctual drive, whereas in Extinction, it's revealed that the zombies have the same drive to consume flesh, even though they don't need it to function. Titans hunger for human flesh, but don't really need it. It's all in the mind or what passes for a mind in the head of a Titan or zombie.
