Are the reapers evil for doing this? (paraphrased from multiple comments)
The reapers are convinced that their existence is the "pinnacle of evolution". At one time, they very likely were a very advanced organic race that became reapers either a) to survive an impending disaster,

because there was
consensus that they had reached the apex of what they could achieve on their own, and saw this new existence as the next logical step (much more likely, in my opinion), or c) some unknown third option.
Continuing my theory, I think they discovered FTL themselves, and needed huge crafts to construct the mass relays, the reapers may have simply grown out of such a craft.
Look at it this way:If there were no asari, salarians, etc., just humans, and we had made those discoveries, FTL, mass relays, the whole smash, then spread throughout the entire galaxy, what would come next? Would we still be driven to expand and discover? We may try to reach other galaxies, but how would we do that? Or, would we simply seek immortality by uploading our consciousness into one of the great machines we had built? The relatively slow passage of time, combined with our short lifespan, are the main factors limiting our technological growth as a species. "If I have seen farther, it is by standing on the shoulders of giants" isn't just a quote from Newton, it is a necessary truth for all advancement because no one lives long enough to make discoveries without basing them on those that came before. Even our most brilliant theoreticians and astrophysicists are crippled by how little they can observe based on the passage of time.
Therefore, to make further discoveries and observations, this hypothetical advanced race may have seen the first reaper as a necessary step toward further advancement of their race. The reapers may actually be the inevitable, end-all-be-all of organic existence (or at least one form of it), when given enough time and technology.
It is further plausible that given such an existence, in which time means almost nothing, what kind of big-picture problems would such a race face? Given the standard 50k year cycle, there have been 740 cycles since the derelict reaper died 37 million years ago. Being supposedly vastly advanced machine/organic hybrids with quadrillions of minds in consensus, one must realize they are doing this stuff for a reason (even if it only makes sense to them), and that reason is probably not just to be evil jerks.
Assuming their reason is a serious concern to the long-term survival of sapient life, they would rightly give no more thought to harvesting us to save countless current and future reapers (who are again, each preserved civilizations in themselves) than Sheppard gave to the destruction of the Bahak system in Arrival. Each thought it was necessary for the greater good.
tl;dr version: We may be making a mistake in fighting against the reapers.This is their version of reproduction; gaining a desirable variability within their population by harvesting the most promising species each cycle. But for what long-term goal?
I really, really, hope we find out.
