Questionable ethics - Living Memory

[AlysCamoa]

I'd really love for you to direct me to the moment in the MSQ where we murdered innocent Garlean citizens and children.

I see somebody has a strong grasp of rhetorical questions. We (the Scions) didn't do any of those things, precisely because we're capable of differentiating the actions of a state from the actions of its constituent citizens. So killing the Endless merely because Sphene did something makes no sense, given those previous cases.

But, we're forced to do so anyway because the (poorly written) story says we have no time to do anything else (despite Cahciua's plan specifically intending to speed up the thing we're trying to stop). Okay, so be it. Why do we feel good that we had to choose expedience over ethics? Why are we having a sing-along ending?
