Dude's basically an unsympathetic Ginko from
Isekai Samurai. Not only does he want to die in battle, he wants everyone else to live/die that way as well, and is willing to drag everyone else into his own mess.
Hell, in a setting like this, just go become an adventurer and make a name for yourself on the battlefield as an example for others. There are tons of ways to show off the "strength is everything" philosophy that doesn't involve dragging a whole country into your elaborate plan for suicide.
