The Reason why Law can't kill Kaido by simply taking his heart out and stabbing it - One Piece. It's very simple. Law's Ope Ope no Mi devil fruit grants him no cutting abilities. Law needs to be strong enough to cut and kill someone to perform his surgeries.
Law is known to use Haki only the basic one Law dont rely too much on them since he rely on his DF.
During the Onigashima Raid, Law confirmed that he cannot move Kaido around due to his strong Haki. Kaido also managed to knock him out with his Raime Hakke, which forced Law to retreat even though he had backup from the other Supernovas. Simply put, Law isn't going to last very long by himself.
As they clashed, Smoker demanded answers from Law, some regarding on who Law was working for, indicating hidden motives. Law managed to gain the upper hand by stealing Smoker's heart with his Mes attack. While Smoker kneeled in defeat, Law commented that he did not have to tell him anything.
Law has a plan to kill(or defeat) Kaido and the reason is the connection between the emeperor and Doflamingo himself(smile's factory). Sure he wanted to defeat Doflamingo in the process, but the plan against Kaido exist anyways.
Also, Shanks is one of the few people that Kaido believes is capable of fighting him.
Here's why Zoro killing Kaido in One Piece's Wano Arc wouldn't add up to the show's plot in the long run. One Piece's Roronoa Zoro is one of the strongest members of the Straw Hat Pirates, second only to the Captain, Monkey D. Luffy.
Law's crew are notably weak compared to Luffy & Kid's to the extent that they struggle with Rayleigh's Haki at Sabaody. This is because Law was never gathering a strong crew to take the throne, he was gathering friends to travel with him until he could reach Dressrosa.
What is the Will of D? The Will of D is a concept that connects the various people in the One Piece world with the initial D in their names. While not much is known about it, its bearers have all been shown to have a strong resolve and have made some sort of notable impact in their lives.
Boa Hancock is the Empress of Amazon Lily and she is the captain of the Kuja Pirates. She is a fearless fighter, who is not afraid to rebel against the World Government. Boa's devil fruit makes her an incredibly dangerous opponent as it is almost impossible to avoid her attacks. She can use all three types of Haki.
However, that's not to say that Kaido has never lost. It is a known fact that Kaido has lost to his fellow Yonko and the Navy a combined 7 times and been captured a total of 18 times.
Kaidou is a middle-aged man who cuts an imposing figure due to his extreme height of 710 cm and the bulk of his muscles, making him dwarf normal humans.
Garp is a Vice-Admiral of the Marines. Being their strongest known member in history, there's no denying that Garp is capable of taking on Kaido. He's previously fought against the likes of Rocks, and even Gol D. Roger.
Conqueror's Haki, also known as the Haki of the Supreme King, is the rarest form of Haki that only a few people in the world of One Piece are born with. Unlike the other two Haki types, Conqueror's Haki can't be learned through training and is only possessed by those who are born with the spirit of a king.
It's no surprise that Luffy possesses the power to use all three types of Haki, being someone who aims to become the Pirate King. In fact, Luffy has successfully taken his Armament and Observation Haki to extreme levels, making him a magnificent pirate in the process.
According to Sengoku, Rocks is no longer alive.
The Void Century is a century-long gap in recorded and archaeological history, the study of which is forbidden by the World Government. The events of this period are so important and relevant that by learning them, one is said to become aware of the "true history" of the world.
The mystery of "D." is still unraveling, but we aren't entirely in the dark about what surrounds it.

Ace and his mother, Portgaz D.

Nami is, quite possibly, the weakest member of the Straw Hat Pirates physically, however, her acquisition of Zeus has made her stronger than before.

They were dating before. Linlin was pregnant with his child, but kaido cheated on her.
Probably no, Mihawk can't cut even Diamond Jozu with his one of the strongest slash and King Elizabello's punch can't broke Bartolomeo's barrier. Mihawk can't win against Kaido who had insane strength that is enough to destroy half of an island.
His durability stems from the power of the Uo Uo no Mi, Model: Seiryu, a Mythical Zoan-type Devil Fruit that gives him the ability to turn into an eastern dragon. Kaido's scales are extremely tough due to his Devil Fruit powers, yet it isn't as if he can't be beaten.
