So why include Luffy's "promise" as a reason as to why Jinbe wouldn't die?
Big Mom killing Jinbe when they meet up again wouldn't be included in the vow according to the logic you just used in this post.
Because it's pretty obvious that Oda isn't killing Jinbe at all, and if Jinbe was actually foreshadowed to die, he certainly wouldn't die in some one-off chapter without Luffy there.
And with Luffy there, he isn't going to allow his friend to die.
Give me a scan of Luffy stating that this is the case after he finished the battle. until then, there's no reason to accept this.
You're completely ignoring the point of the entire confrontation.
It's pretty obvious. You don't need Luffy to tell you this, but rather his actions.
You think he's mad because he thinks he killed him? No, he's mad because Doflamingo is the reason Bellamy acted that way.
Plus the panel showing Bellamy's defeated face next to Luffy's rage in this very chapter (yes, this is Oda's depiction, and not Luffy's inner thoughts, but it doesn't nullify it):
This is completely irrelevant.
No, it really isn't. We know he isn't dead, and so does Luffy.
Luffy hasn't said a thing about thinking he's dead past punching him.
And yet Luffy kept reinforcing notion hat he would die if he attacked him during the fight.
If you're using this as your logic, why do you keep on insisting that Luffu doesn't thinking he his despite the fact that he didn't say otherwise?
Just like Luffy/Chopper both thought Usopp would die if he continued to fight Luffy at Water 7. That certainly didn't happen.
A G2, Haki infused punch was exactly what was used against that pacifista.
Even so, it wasn't meant to be seen as a "pacifista blowup" punch. It's a callback to Jaya, just with more strength to it.
Where was it stated that your emotional state affected your CoO?
He was filled with rage yet he could still apparently tell that Bellamy's still alive with his CoO according to your previous statement.
Both of those are speculation on my part. We know very little about how Observation Haki is activated other than it varies depending on the users' skill. Since Luffy is a novice in it, it isn't unlikely that he doesn't know how to control it while panicked or enraged (basically, without a clear mind).
