It makes no damn sense. Blue is 'you can control, but you'll be dead, so nothing is really in control' making it a bullshit answer. Green is 'everyone becomes one, but the Reapers still exist, therefore can control all life' making it a bullshit answer. Red is 'destroy us, but synthetics are gone, until you remake them.' That's also bullshit given the basic reasoning of 'there can never be peace between the two forms of life.'
I went ahead and said

you, Godchild, and chose Red. Got a breath. It ticks me off, and I won't play it again like I did with 2. It really does sour the mood on the rest of the series for me, since you know where it ends up, a thoughtless place.
