Damien's body cringed in disgust. At the same time, he wondered whether he should regret his impulsive action or not.
Killing Luo Tian was a move to provoke Wrath in the same way he provoked Damien. There wasn't much else to it. But in fact, the difference in their power levels made this a feat unheard of.
Damien understood that he could die at any moment, but he simply couldn't stop himself from acting as he wished.
Because that was his end goal.
To stand at the top unfettered by anyone or anything. If he wished to reach that point one day, he needed to embody his beliefs at every step of the way until he arrived there. Otherwise, his resolve would be far too flimsy to see the peak.
And in the same vein, he had to kill Luo Tian. Because if, at this juncture, Damien finally bent to power and authority, he'd cut off his future development.
