@Magi:
The majority of the arc consisted of fights. Half of these fights came to be because of Law. It wasn't focusing on these people like you're claiming.
Like I said before, the arc showcased what happened because of DD's reign and the good majority of it is fighting.
This entire thing is a byproduct of their conflict.
We're weren't talking about "the rest" and the amout of times you've diverted this conversation is ridiculous. Luffy's excuse for fighting now is because Becca bought him some lunch.
He's not. There are several characters who actually have legitimate reasons for defeating Dofla are strong enough to do something against him, including Law.
The "byproduct" is much bigger than the source of conflict. This is already far bigger than Law's revenge plot, with several factions involved.
Like I said, Law's cause is extremely small compared to several other characters.
Kyros, Riku, Viola, Rebecca, Chinjao Family, Dwarves, Fujitora, even Elizabello also have legitimate reasons for defeating Doula. All of them bigger than Law's too.
Just because you like Rosinante doesn't mean he's more important than all other reasons. This conflict has much more than just Rosinante. We're talking about mass slavery, gladiator torture, existence erasing and imprisonment involving millions of people and several countries.
Law started this, but that doesn't mean he needs to end it. Like I said, this conflict evolved way past Law and Doula. Being the start of everything means nothing as Law himself only cares about the start itself and not what it caused.
This is similar to the Marineford War. Ace vs. Blackbeard started it, but the initial motive of Thatch being murdered was irrelevant through the war.
And Luffy in the end is the one all those guys believe can solve it. The gladiators, Royal Family, the other Straw Hats and Fujitora think so too.
