Guys, don't you like the Tutankhamun clue?
In short, the more I think about it, the more I'm convinced that "strangled with a loop" isn't a clue. It could have been, if we found exactly that quote in the wiki (but Google didn't find it), but as Locke showed again, hanging can lead to many things, so it would be a very strange clue.
In summary, we have unclear information, not a clue, about the loop – most likely, 95% it's just the method of murder... And okay, if we pay attention to the fact that the Heroist wasn't strangled by himself, but by a villain from the outside, then is it Balzac? There's a hint about the role – the last line, where it mentions kindness. And there's nowhere else for the clue to be physically located, except in the middle between these two descriptions.
I clearly remember that in some mafia game, there was at least one clue consisting of two words, and it was something like that, with famous profiles. And you had to cleverly connect them in parallel to lead to the same profile. If this isn't a case of a "spoiled telephone" or a misquoted phrase, then it could be that kind of clue. Then, "civilization" and "health" stand out the most? Or maybe "viability."
But I have a feeling that we won't learn more specifically about the methods of creating clues in this mafia today.
