& 238 counts of murder-suicide
Wouldn’t this make the MH370 captain the worst mass murderer in history? If of course, his guilt was proven 100% without a doubt.
If his guilt was proven beyond a shadow of a doubt, then yes, he'd be the worst confirmed individual mass murderer in history, but there are serial killers (e.g., Henry Lee Lucas, Edgar Matobato, Charles Cullen, Luis Garavito, Pedro López, Giuseppe Greco, Niels Högel, Harold Shipman) whose kills are believed to number above 250, even though their number of confirmed kills is less than 238, & of course, none of this considers whether or not dictatorships led by individuals, or even just organized crime syndicates led by individuals such as Murder Inc. & the Angel Makers of Nagyrév ought to count here.
Henry Lee Lucas probably only murdereder 1 person, the rest of them were just confessions that were fed to him.
