Fate and destiny are a big part of their culture. This is why you always see fortunetellers in mangas and karate movies.
People lately have been less accepting of fate and destiny precicely because of that (points to your username). Besides, oda is going to turn it over it's head when Luffy gets presented with the choice that Roger had to make in the end and pick a third option.
In terms of the chapter. It was Meh, They should of put Hodi in jail years ago if she informed them
AND SHIT ALL OVER HER DEATH MOTHER'S DYING WISHES!!!! WEEEEEEEEE
Even if shirahoshi wouldn't hate him, his brothers and father would, and would have taken the chance to execute him.
Luffy needing blood was cringe worthy after all the battles Luffy been through that left him a bloody mess.
Most blody battles didn't involve combined gear 2 and 3, the moves that make your blood go faster and makes your body expand.
He didn't get any particulary big wound since he started using the gears until now. Maybe Lucci's bite, but that one didn't get like 4 chapters of focus and seen dripping blood all over.
Einess Loby was mostly Rokougan and gear 2 exhaust.
Thriller Bark was purely hp expended using techniques to defeat Moriah before the time limit.
At shabody's end Luffy would be able to go another round, just heartbroken.
Impel Down round one was poison, all the bleeding was under heavy hormonal treatment.
At the war, he didn't get any terribly nasty wound untill the end, with the one that was cauterized inmediatly.
Before the fight with Akoiji Luffy was a lot more likely to get a big open wound, (Arlong's arm bite, Crocodile's "using blood to punch you", I think that Enel managed to hit him with the pointy end of the trident, Foxy did draw blood) but since then this one was the only bleeding wound to get focus.
