The Genophage was right, and you and paragon Shepherd can go suck some morally uptight bollocks.
Even when I’m playing paragon, I will generally go renegade options when the Genophage is involved, since I wholeheartedly believe it was the correct choice.
I remember once playing XCOM: Enemy Unknown. I was assaulting a medium-sized UFO, and I’d reached the front door.
Hesitant to just run in through the front door, I sent half of my party round, so they could break the wall on the other side and flank the enemies inside.
It took a few turns to maneuver my forces round the side of the UFO, and as I did so, an alien squadron spotted my three guys on the door, and they started blasting. With my flanking team still well out of range, I had to sprint them forward to help - right into even more aliens.
My men got decimated. Six turned into four, then three, until only two men remained against well over a dozen dangerous aliens. And so remain they did. Thomas Bassoon and Eduardo Garcia were immortalized as legends that day, as they fought off multiple alien squads with just the two of them.
When XCOM 2 rolled around, with a notable time skip, these were the two soldiers I grandfathered in. Two veterans, here to fight the aliens once more.
Side note: In the tutorial for XCOM: Enemy Unknown, your squad of four is scripted to only have one survivor. Eduardo Garcia was that survivor.
Notably, 22 minutes from when you see the nomai statue. So the commenter could have spend over an hour in the tutorial area, and then quit before experiencing much of the actual game
