Maybe Netero really is just forced by his current standing to kill the king. Those dudes in black suits may have more clout than we think.

I actually find the situation to be quite interesting. The king who everyone hates is suddenly willing to negotiate and wants to save humanity, while the hero we were rooting for is now influenced by politics to kill the changed king.

Netero is also really smart when he raised the name condition. It not only forced the king to fight, but also handicapped him. A rook and bishop handicap is pretty huge, but that is of course assuming their levels were close in the first place, which does not seem to be the case.
