i have always agreed with zkk in that regard. but i still have a question..why would zoro go out of his way to kill a downed opponent ? he doesn't have hatred for kaido..and he didn't kill doffy when he was defeated by luffy..why this time? what changed?
Arc ends-> News goes out across the world
Page 1 headlines Luffy topples Yonko, bounty raised to 5 billion!
Page 6 article, Zoro kills Kaido?
What world do people think this is happening? This is Luffy's big W, and nothing is overshadowing his ascent, executing someone would be a bigger news story, even if it isn't really a feat.
Oda loves to leave villains alive so they can wallow in defeat and copium as they see Luffy rise to become PK, Luffy takes down Kaido it undoes 20 years that Kaido has worked to rise to this point, it's not as simple as just returning to Wano when Luffy leaves, at that point his dream of becoming PK will be crushed and Luffy will be racing to Raftel with most of the Poneglyphs in hand and a superior personal battle strength and fleet to Kaido.
