9. Good thing. Or well, maybe not "good" as war is hell, but a justified and necessary thing.
To suggest that the burning alive of perhaps 100,000 civilians--men, women, and children--was in any way a "good" thing is an obscenity of the first order. If the shoe had been on the other foot and Japan (or Germany) did the same thing to the U.S., we would likely view it as a war crime even if, in that alternative scenario, it had been us who started the war.
It's not even clear that it was "justified and necessary."
