Hunter Hunter exists very clearly within the pragmatic master analogue. The stories morality is intentionally skewed and muddied, contrasting Netero, the human, with the Monster, Mereum. Netero should be easy to root for, but instead he is often described in grave terms, and called a monster. And Mereum should be easy to despise, but instead he acts quite reasonably, insisting that violence should not the method through which they solve their problems.
This goes further if you look at their specific approaches. When Netero tries to attack him, Mereum insists that he doesn't want to fight, and since he poses no threat to Netero, it would be unwise to fight him. And this is true, as by the end of the episode Mereum has gravely injured Netero. Mereum makes an argument based not on morality, as he had made his plans for mass slaughter abundantly clear, but on pragmatism.
But Mereum isn't the only one who exercises such tactics. Netero deliberately takes steps to ensure Mereum's servants are not nearby to aid him, and then once they are alone, ruthlessly exploits Mereum's weaknesses to try and kill him. Unfortunately, Mereum is too much for the Chairman, and manages to weather this assault without severe injury.
But still, Netero's failure to kill Mereum does not undermine the pragmatic master analogue. Netero's tactics were savage and ruthless, but Mereum was simply too powerful. He should have taken his opponent's advice and ran.
