Perhaps the Reapers are doing this simply because, well, Humans are Illogical by nature. Look at the turians, for instance. They'd leave their mother to die in a plasma fire if it meant getting loads of money to, say, cure a disease like Kepral's Syndrome, or whatever equivalent to Cancer they have in Space. It's like how the sea erodes a shore; it just keeps hitting it until the weaker stone crumbles. With part of it broken off and little support, the shore crumbles into the Ocean, which is then assimilated to continue breaking down the shore.
