I understand the Catalyst's logic perfectly. How could I fail to? Science Fiction is full of examples of AIs turning on organic life "for it's own good". From Isaac Asimov's "I Robot", to the Borg, to the Cybermen. It's a common trope bordering on cliche. I just don't think it's a particularly interesting or original motivation for the main antagonist of this series.
As others have posted its also a hopelessly inefficient way for the Catalyst to fulfil its objective. After "preserving" a species, it pours it into what is essentially a warship, and then periodically throws it into battle. Where it might get shot to pieces, or blown up from within, or eaten by a Thresher Maw.
Of course one might argue that it is not even interested in the preservation of individual species. It's more interested in preserving organic life in general, against the unlikely possibility that some sort of omnivorous, sentient nano-goo might be accidentally created by some reckless organic species, and then go on to spread itself through the entire galaxy and consume every living thing, on every world, down to the last bacterium. Given the vastness of the galaxy I find this almost as unbelievable as Synthesis. I think my Shepard's response to the Catalyst regarding this entirely hypothetical apocalypse would have been "Let's cross that bridge when we come to it, shall we?"
Then of course there is the issue that the Leviathans were not interested in preserving some vague concept of organic life for its own sake. They wanted individual species preserved as they were, so that they could continue to control them, and extract tribute from them. This, however, would be hard to do after the catalyst murdered 99% of the Leviathans, and then transformed their potential thralls into a semi-synthetic form that they might not have been able to control even if they were alive to do so.
The Catalyst has been busy preserving slaves for masters who (very nearly) no longer exist.
These are the actions of a pitiful, broken AI, trapped by its own logic. Hardly a worthy opponent, or a very satisfying one to defeat.
