He was placed with that choice from the start of the raid. The 2 targets were kaido and orochi. He could have gone after either.
Where exactly was the choice that Zoro had? Kaido and Orochi were believed by the alliance to be together and they were until Kaido killed him.
The two targets were together.
Bro chapter 977 just before they land on Onigashima they were discussing the plan to kill Kaido. Then when Luffy makes the toast he says “First we deal Kaido, then Big Mom and Orochi”.
In chapter 979 the diagram and dialogue mentions Kaido and Orochi castle. For all they knew they could have been in the same place.
Chapter 982 shows another diagram of the castle and places Kaido and orochi together, they even talk about saying that they’ll both be in position.
Chapter 983 Orochi and Kaido are together just before the plan to execute Momo.
The Strawhats are all mentioning about fighting Kaido and even after the info about the alliance between Kaido and Big Mom, Kin says their enemy is “A Yonko” whether they were following it in systematic order or not who knows but they were always going for Kaido first. Like these were all the reason why they are mentioning conserving energy before going to fight Kaido. I’m not even arguing against this and you’re just saying I’m talking shit or asking if I’m dumb?
