What message could Zaroth hope to send by showing the beheaded head of his opponent?
It didn't make much sense.
The answer was simple, even though the crimson mist had faded, its effects on Zaroth's mind still remained.
So he wasn't able to think clearly at the moment.
What could he hope to achieve by showing the head to the audience?
After all, the people had reacted strongly when they saw that he had killed before, and yet he had done it again.
Sure, it was much cleaner than before, as rather than making his opponent's head explode, he simply beheaded it.
But that didn't make it better; a murder was still a murder.
Not to mention, Zaroth had locked his gaze with the emperor.
His actions stunned him for a few seconds, if he did them, it must have meant that he secretly wanted to do them.
'Because I want to!' This was the conclusion he came to after several seconds of thinking.
He wanted to kill the assassin, so he did.
