My point is what is driving those religious fanatics to do what they did, is very likely not what was driving Paddock.
I think he initially started simply as a challenge - he appears to have developed an interest in this after several Islamic mass shootings/killings in concert venues last year - and then, either intentionally or through seriously bad luck for us, met somebody who encouraged him to “give some meaning to his life” by converting and becoming a jihadi.
ISIS claimed he converted 6 months ago, which I think would have been on his last cruise to the ME, but that was several months after he started scoping out hotel rooms that overlooked concert venues.
