Ves was done playing the Oscillating Fist's game.
He had taken over the negotiations because he refused to let this rebellious bastard manipulate the Dark Apostle like a puppet master.
He made a reckless gamble. Ves knew that he was pushing his luck. The consequences of noncompliance were drastic. The Ascended Giants watched closely in order to see which of the two had earned the right to lead their group.
So far, Ves did not think he had been doing so badly. Since the Oscillating Fist was allowed to act like a scumbag, he should be able to do so as well.
In fact, he ultimately believed that acting in an assertive manner was key to winning over the Ascended Giants. They clearly wanted to be led by an alpha figure. They rewarded boldness and rejected cowardice. Their primitive sensibilities drove them to worship the strong.
It just so happened that there were many different ways to express strength.
