Well, obviously! They did it because they could. That is why power-hungry entities do everything they do. Because they CAN! Naked self-interest is what drives the Cosmos, as you wretched human beings will soon find out when my unstoppable legions of Arcturus and Thoth take over your miserable speck of cosmic dust, called Earth, and turn it into an intergalactic rest stop.

We will slice, dice, whoosh, and squoosh the lot of you. You will be liquidated. And we will enjoy it too. Immensely.

Where we differ from your corrupt political leaders is in this: We are totally honest about our ruthless self-interest. They are not. They pretend to be "nice". They pretend to be democratically inclined. Ha! We have never pretended anything of the sort. The nice are sheep for the slaughter. Only the strong and merciless   survive. Predators rule! Others drool!

The Omnipotent Krill has spoken!
