That's a good theory, but here's a little more food for thought: the reason the Gems do what they do is because they're natural Capitalists who exterminate all life on planets, and then sell the planets to the highest bidder like in Dragon Ball Z. But the Crystal Gems rebelled and started a civil war. By the end of the war, the Galaxy Warp was destroyed, almost all of the Gems were forced to regenerate (which went wrong thanks to the Gem Queen who corrupted the rebels and turned them into monsters, all the while filling their heads with lies), and the survivors found out Lapis was a spy and turned her into a mirror to silence her.

In the season finale, the Gem battlefleet will arrive and swiftly arrest the surviving Crystal Gems for high treason. The male Gem commander in charge of the fleet (who I envision as being voiced by Tim Curry) will be disgusted with Steven, who he calls a "halfbreed monster" and tries to kill him, but Steven defeats him and smashes his Gem. When he finds the Crystal Gems, he basically gives them a massive tongue-lashing for lying to him all these years, to which they are driven to tears.

Lapis then returns to Earth, realizing the xenophobic ways of the Gem species, and springs the Crystal Gems just before their execution. It is at this point she becomes an official member of the Crystal Gems. A massive battle between the Gem battlefleet and the military forces of the world ensues, and the residents of Beach City hold off the Gem steamroller attack, killing many and causing others to flee in fear. The Gem battlefleet is then forced into retreat, but not before a bunch of Gems rallied by Lapis (named Ruby, Sapphire, Diamond, Crystal, and Emerald) defect to the Crystal Gems and set out across the world with the same mission as the Beach City-based gems: defend humanity. Lapis, meanwhile, stays in Beach City and begins adjusting to Earth life.

But the Gem Queen is furious with the defeat of the battlefleet, and after some thinking, orders construction of a new superweapon to destroy all life on a planet but keep the planet and its flora intact. Thus begins the Gem Civil War arc...
