Raith's mistake was overestimating himself and taking lightly the abyss' warning. Since he now understood Cor-Ellion's ability, he thought it could put an end to it.
But the fact that he understood it very well didn't warrant that he could stop it. He was nowhere near the royal asura in all deciding factors of battle, strength, battle IQ, speed, endurance, intelligence, and even [Multiple Cognitive Resonance] was often caught off guard several times because the control Cor-Ellion had on space affected it.
What Raith's eyes couldn't see coming, there was no way it was possible to analyze it. And so Raith was stuck in a limbo of dying and resurrecting.
