I believe the Reapers themselves have a lifespan. If they didn't have galaxies to OM NOM NOM, they'd eventually die out, plus they're machines so they cannot breed. Therefore they build and destroy galaxies in order to sustain themselves. Or maybe, if a Reaper is not engaged in war for a certain amount of time, they die? Therefore building galaxies is a way for them to satiate their incurable urge. Makes me wonder too... do the Reapers themselves have gods?
