Come on, Netero had no choice but to kill Meruem, regardless of whether he wanted to or not. What does it matter if Meruem killed whatever number of people? The question was WHY Netero wanted to kill the King. He wasn't doing it for vengeance for those who died, or even to save lives. He clearly stated in the ANIME that a person in his position cannot allow what Meruem wants, and this was all before Meruem's declaration that he wanted an equal, peaceful world for the humans. The human preserve and killing the rest thing is a misguided imagination. Meruem's statements contradict that. His actions afterwards contradict that.

Also, why is it so obvious to you that he cannot trust Meruem? Why didn't he even hear him out? He clearly stated the reason. Because he might be swayed, which basically means made to trust Meruem. He does not have that option, so he did not take it.

The funny thing is, everything that happened after simply showed how great a ruler Meruem could have been. Benevolent and fair, far better than any human ruler in the HxH world currently. He was also imba so he would not have worried about military pressure outside of nukes hitting him directly.

Are you the neg repper? If so, you could have just replied in the thread.
