It raised a few eyebrows, but I think I agree with the author's rationale - the Leviathans actually do seem like the kind of people who would develop a nuke to eradicate cockroaches. Honestly, their whole explanation of their motivations always reminded of how, in certain strategy or simulation games where I'm (apparently) the dominant player, I'll devote vast amounts of effort to solving a trivial problem solely for "the lulz".

In fact, I'm not sure how different this is (in terms of disproportionate effort, anyway) from the actual reason the Reapers were built.
