Basic literacy is dead. You can't really "genocide" something that isn't alive in the first place. If you were to create a prospering population in SimCity and then delete it, would that be genocide? That's basically what you guys are arguing. The main hiccup of course being that in this example, the computer running your simulated city is being powered by a regular blood sacrifice from your neighbors, and you keep having to kill them to keep the game going. If your remaining neighbors knocked down your door and forcefully shut down your computer, that would be self-defense, not something cruel they did just because they have some vague and baseless "agenda" against you.

The Endless had to go because Sphene was quite keen on wiping out the rest of Source and all of the Shards (which would be genocide) just to keep sustaining what was basically a glorified simulation.
