Power was addicting. Power corrupted, but that wasn't the kind of trap Khan had fallen into.
A hammer begged to be slammed. It was the sole purpose behind its existence.
A rifle had to be fired to avoid accumulating dust and other hindrances that would make it stop functioning.
In the same way, power had to be used. It was an intrinsic drive that went against merely leaving it to rot away and more.
Khan's predicament was also deeper and more convoluted. He had spent years or longer unaware of his hatred toward the very power that had made him one of the best warriors in the regulated universe, only for Liiza to fix that in his last battle.
The fights on the Nak's home world obviously couldn't suffice to test that revolutionary change. Yeza had also been born in that period. Khan had even gotten rid of his nightmares, completed his mission, and had a war to consider.
