Since First Guardians are omniscient, didn't Bec know that prototyping itself with the kernel would cause Jack Noir to be near-indestructible?

It’s hard to tell if Bec, given he’s a Dog, also had Omniscience. Even if he knew it would lead to Bec Noir being created, however, it’s just like Vriska said. His existence is pretty much necessary for the Troll and Human Sessions to become intertwined and the Alpha to go as it needs to go.
