Why does Kaido want to kill Whitebeard?


According to Wikia, [Kaido's
article](http://onepiece.wikia.com/wiki/Kaido#Yonko):

> [...] Kaido and Edward Newgate were not allies, yet would not, under normal
> circumstances, provoke each other. However, Kaido saw the opportunity to
> take down his rival prior to the impending Battle of Marineford, and did not
> hesitate to take advantage to attempt so.

I don't know why Kaido wants to kill Whitebeard at first place. Are there any
evidences from the series that suggest so?




Pirates are pirates. If they see a chance, they will take it. Also Kaido could
have gained much with Whitebeard's death.

According to [the Wikia article about the
Yonkou](http://onepiece.wikia.com/wiki/Yonko) (sorry, I couldn't find the
chapter where they actually say this):

> [...] the Yonko stuck in a deadlock situation [...]

Ideally Whitebeard's death would have given Kaido the advantage he needed to
advance in the New World and eventually become the Pirate King. He just didn't
expect Shanks to help out Whitebeard, or Blackbeard to be so swift taking his
place and becoming a Yonkou maintaining their deadlock.
