Uh. The russians armed them. Trained them. Gave them logistic support, information, and direct military intervention. Gave them mercenaries. Generals. Troops. Tanks. Artillery.
Without Russia's intervention this never would have been bloody, as the rebels would have been largely unarmed, never had as many fighters, mercenaries. And if it was still bloody it would have been over quickly, and we would all be at peace now.
So yes, Russia created the rebels.
Regardless of their role in Maidan and buying off Yanokoych.
