Its not a main theme of the story.

The "cycle" of the Catalyst is it projecting its core programming, to resolve its creators conflict with a specific group of synthetics, onto galactic history.

Just as religious people see god behind everything, the Catalyst chooses to see organic-synthetic conflict behind everything. That's just how its programmed. That doesn't actually mean its right.
