Khalos had lost all of his reasoning and the only thing left in his mind was the desire to kill Ren. He was blinded by uncontrollable rage and continued to destroy everything in his way. There was nothing else in his sight except for Ren. The pride he once had as a New God was gone, the drive he had to become stronger had disappeared, the skills he has honed for centuries were nowhere to be found, everything he ever was and ever will be was devoured by the branch of the ORIGIN.
After accepting the strength granted by the Branch of the ORIGIN nothing was supposed to be left of Khalos but madness, yet despite the insanity, the branch of the ORIGIN gives the bearer, Khalos was able to maintain one single thing and it was his anger at Ren. As he kept on punching through the layers or walls Khalos suddenly stopped and backed away.
