Let's see...
In ME1, I thought they were, well, kind of like Chtulhuian eldritch abominations. There was no point in pondering about their reasons, since they operated on a blue and orange morality that was completely removed from human logic. I was okay with that.
Then in ME2, it turned out they were not just killing but "harvesting" organics and turn them into reapers. At first I really didn't understand why they need organic components and why they made a giant terminator out of human goo... which again, kind of baffled me, as I really didn't understand the point behind doing that. I mean, what is the difference between liquefied human and Krogan? At that point it's both just big chunk of liquid lipids and proteins, so what difference it makes what species it came from? X_X
But then again, I was still okay with that. I was like "Sure, so they need organic matter from advanced races (for some weird, incomprehensible reason) in order to procreate, so they wait for advanced races to develop and then swoop in to harvest and make Reapers out of them. It's how they procreate. It kinda makes sense.".
And then came the third game, which confused the hell out of me.
So, at this point, it is revealed that the aforementioned liquefying and procreation goodness was just a means and not a goal, because the goal was to kill all advanced races so that they can't make synthetics that would kill them in the long run...? 0_o?
Okay, I get the idea of cycles. Actually, I think it kind of sort of makes a little sense, and I have a good parallel for that:
On our very own little blue-green planet, forest fires are actually part of the natural cycle, whereas the fire destroys the vegetation so that a new generation of life can take its place. It kind of makes an utilitarian sense to say that, in this context, the Reapers are the fire that wipes the forest clean so that a new ecosystem can bloom in its place until the next fire. It would actually make a lot of philosophical sense if this was the Reapers' motivation, enforcing this cycle so that the young species would have their chance to expand without being overshadowed by the old races and whatnot. It's arguably a flawed logic, since we are talking about sapient species here, so who says they won't be able to solve the issue on their own, but it would still be something that can be accepted for a motivation. HOWEVER!
The problem here is that this is NOT their philosophy. Actually, they don't have any of that at all. I've heard many people say that they use machine-logic, but that's not true. They don't use logic at all! Logic is about taking all available variables into consideration and making the best choice based on those. What the reapers have is a fanatical, unquestioning belief that "All organics will eventually make synthetics that will destroy all organic life", something they have no basis for.
They believe this because, as they said, it "always happens like that"... But here's the thing: we never saw that. Even THEY never saw that! Why? Because they destroy organics BEFORE they could make all-genocidal-synthetics, so they are preventing something that they have no proof for it would even happen! There is no "wheel of life" here, no galactic seasons, they just fanatically believe that this synthetic-apocalypse would happen based on an example we are never given and they refuse to use logic to fix this hole in their motivations. In short, their leader, and AI (who is by definition supposed to be all about cold logic) refuses to use logic. Bad writing or some really stupid, fanatical villains? You decide.
Also, one more thing: There is something I kind of noticed about the Destruction ending that I haven't seen posted yet. That ending says that using the Crucible will destroy all synthetic life in the galaxy including Shepard, which is just stupid. However, what if it only destroys/shorts out Reaper-tech? It would actually make sense, since:
-The Reapers are obviously made of that stuff, so they are destroyed
-The Geth had been modified with Reaper-algorithms at the end of the Rannoch-campaign, so they are destroyed
-EDI was partially based on Reaper-tech, so she is destroyed
-Some of Shepard's implants are based on reaper-tech, so he is killed
Now thinking about it, it's kind of funny how the Reapers uphold the cycle in order to keep organic life being wiped out by advanced synthetics... while the synthetics had only gotten this advance because of Reaper-tech...
