Coincidence? I think not.
An interesting hypothesis. You don't want to get into Jhin's head though. Trust me, I'm awake at 2am for making that mistake.

I like this Theory.
The theory that diagram is referring to is the world-famous aristotelian "Three Act Story Structure" which refers to how, in theatre, a story is divided into three parts, not four, of a Beginning, Middle and End, and between them are divided introduction/exposition, introduction of a conflict, rising action, climax, falling action and resolution.
Sorry dude; nice idea and I appreciate it... but it doesn't follow.
Ima be honest, I thought he just killed four people because it would be a good team for him to play on :v
There is also the trope that "Four is Death"

Could just be a coincidental thing, but it's certainly not the first time a character and the #4 have been associated with death in general. As a former student of Theater though, I do like your suggestion - ties in better with the whole "artistic" side of the character's lore (at least as it has been revealed thus far).
