So Kaidou was beat 7 times but captured 18? How do those numbers work out? I would understand being defeated more than being captured as you could run after losing but how in mathematics can you be captured more times than being defeated?
This or maybe Kaidou is just stupid and fell into traps :|He probably gave himself up just so that they could kill him. Similar to what Roger did, he wasn't defeated, he gave himself up.
