So he's only lying about control? The other 2 are totally legit? I don't think you can apply that logic to only one of the choices.
I argued that where exactly?
You don't drop a god-child into a story with 8 minutes left to go. It invalidates
any damned ending to come after it.
You have three full games worth of "control is not the solution" presented to you from various angles, and then some god-child drops out of fucking nowhere and is all like "no dude, control will totally work" and
you buy it? That's less about trusting the god-child and more about paying attention to thematic undertones that have run throughout the whole series.
I'm not happy with ANY of the endings. Everything beyond Maurader Shields is shit. Sloppy, sloppy shit. (actually, moving the Citadel was pretty bad...)
I'm not happy about being offered 3 endings that don't make any sense in the universe in which they're presented. Assume the god-child isn't pulling a fast one, and its just the writing that's critically broken:
Control should be avoided according to the established narrative because it never ends well*
Destroy should be avoided because you commit Gethocide--that ain't fair
Synthesis is so poorly explained and the repercussions unknown (remember, we know that control=bad and genocide=bad) that it remains the only option to exercise with a semi-clear conscience.
AAAAAAAAAHHHHHHHHHHHHH!!! Why do I still care?!!!
