Kid has many good reasons to fight Kaido.
What is the explanation of this shameful behavior?
- Kaido has beaten his crew and made Killer becomes laughter
- Kid boldly announced to revenge Kaido and threaten Luffy not to interrupt
- In chapter 1010, He knows that Luffy got beaten being unconscious and that Zoro is half-death
What is the explanation of this shameful behavior?
1- If we talk about strategy, he is doing the right thing to keep BM away from Kaido
2- If we talk about accomplishment, him taking on Big Mom is equal to taking on Kaido... so... it's the right thing for his notoriority too, instead of splitting the credit with Luffy on Kaido
3- If we talk about Killer laughter, it was Orochi, not Kaido
Lastly, Kidd already had beef with Big Mom pirates before and it was set up TWO TIMES:
- During Fishman island he sank two ships for her according to Tamago
- During WCI is was said he entered her territory, and in Udon Kidd expanded on that
Makes 100% sense to me
