Morty and Rick in “Unfinished Business”

Why are they attacking us? I-I-I helped them!

You gave them proof that there was something bigger and scarier to unite against, you little idiot! They would have gone back into the Dark Ages for a couple of generations, but instead, they dedicated themselves into making universe-destroying, un-thought-out technology like time travel, all so they could try to kill a little shitsack on Earth who couldn't let a dead snake be dead even after it bit his ankle! Next time, stay in the fucking car!
