Perhaps, but what made the Reapers? Perhaps whoever/whatever made the Reapers also made the Relays and the Citadel, and the Reapers are just using them for their own goals. And what if the creators of the Reapers are still around, and are just waiting for the right moment to strike? Wouldn't that be quite the plot-twist, that the Reapers aren't the biggest threat to the galaxy?
