Aknarel was still in meditation inside the prison created by the enemy Origin Gods. He knew that he couldn't flee, so he didn't try to waste his energies unless some of the enemy Origin Gods seemed to have the intention to leave.
He definitely would let all those Origin Gods trapped with him there. They were the greatest danger to other people in the universe, so as long as they were trapped, the other members of the faction wouldn't be so dangerous.
The main difference between Aknarel and the enemy Origin Gods was that Aknarel couldn't get information from the outside while the enemy Origin Gods could.
After all, they weren't in a prison like Aknarel. They were just forced to remain trapped inside the planet to prevent that Aknarel escaped. Once Aknarel escaped, there was no doubt he would call reinforcements that would wipe out their faction.
