The Catalyst doesn't have an objective point of view. Anything it ever witnessed would be irrelevant since it already decided the only way to "preserve" life is to snuff it out. The Reapers don't actually care about peace since they reap on a cycle. There is no room for peace or observation in that.
I disagree, as the ebb and flow of events in the cycles happen independently of the Catalysts action of harvesting the galaxy. It observed that conflict between synthetics and organics arises with certainty, and that when it does, synthetics eventually win. On cosmic average. The occurrence of the conflict represents statistical data to the Catalyst acquired over millennia of controlled experimentation, which is essentially what the cycles are, and (assuming he isn't flat out lying about it) he presents it as such.
His solution is to "preserve" life by mind-uploading, basically. A solution to a problem that he views as statistically inevitable.
So yes, he represents a biased point of view. But his bias doesn't seem to be in how he interprets the data he gathered, it is instead in how he interprets the solution to the problem.
A reasonably intelligent Shepard would say, okay so assuming you aren't BSing me, you have gathered data over eons that says this conflict is an inevitability. It would be idiotic to try to argue with that. What I instead argue with is your ideal solution, which no organic would think is a good idea.
