Why do farmers protect their livestock from predators? Because their duty is to protect their animals, not promote the circle of life. The Reapers were setup as caretakers of organic life, and thus will do ANYTHING required to protect it, even if it means killing a portion of it.
First of all, the "livestock" thing did not come up in the ending at all. It was implied that the harvest was to "preserve" organic life. Ie they were doing us a favor. Self interest did not factor into the sharchild's explanation. He made it sound altruistic.
And before you say again "well all non-spacefaring life lives" yeah, oh boy, the dogs and other non sentient species get to live. Big whoop. And other civilizations will flourish...until the reapers kill them too. But hey, by killing those guys we prevented them from getting to big for their britches and doing something drastic that would damage other up and coming civilizations...who we're eventually going to kill anyway.
Gee, if everyone ends up dying a horrible death anyway, what's the damn point? Couldn't we just step in and protect organic life from any major threat, synthetic or organic? Naw, we'll burn everything. To help them! Yeah, how is this helping organic life again? The galaxy is big but still eventually you're going to run out of sentient species (after all, it took Earth 4 billion years to produce just one). Reaper self interest I can buy, but that's not the explanation we got.
Secondly, the reapers are synthetics themselves. They're pretty much exactly what they're supposed to stop. "Well, what if a new synthetic species comes along that has no restraint and kills everyone?" you'll probalbly say. Well, since the only candidtate we've seen, the geth, were pacifists until the reapers themselves came along. And there's EDI....no wait, she was a good guy too. Hmm, it's almost like the idea of inevitable synthetic war is bullcrap. Might as well say that organics will inevitably conquer each other and enslave each every race in the galaxy. Between the bloodthirsy Krogan and the racist Protheans, the precedent is there, more so then "all synthetics are evil."
Theoretical synthetics that don't exist and have never come close to existing during the story that are marginally more ruthless than the real, very ruthless synthetics we already have is not a compelling threat or a good replacement to the perfectly functional villians we already have. The game provides no proof that synthetics will inevitably destroy organics except the reapers themselves. It's all around dumb.

Which makes them effective villains because you want to punch them in their faces and tell them they're wrong.
Except you can't.
