Ask?
I'd tell them
It was a mistake, it serves no purpose. You idiots doomed the galaxy to a billion years of endless cycles of death for nothing. This is all your fault. And as soon as teh Reapers are dealt with, you won't be the lesser evil anymore.
You're going about this all wrong. Billy the Squid and his Hole in the Water Gang will just roll their bioluminescent eyes and go on about apex this and transcendence of lesser species that. You use them and their thrall teams, then you dispose of their orbs, and then deal with them once their usefulness is at an end. To forewarn is to forearm.

Joker: Hey, Shepard, how's about we gather the crew in the lounge for an anniversary vid?
Shepard: Again?
Joker: Oh pff we all know you live for this stuff. C'mon it'll be fun.
Shepard: Well if you say so.
[in the lounge]
Shepard: OK so here we are, sending a care package to our friends on 2181 Despoina,
Garrus: We hear this story every year...
Shepard: Shhh here it comes. Wait for it…
Javik: I watch this vid every weekend and the suspense gets me very time.
