Excuse worked if it was only like 7 days not 20 years.
Is Kaido that dumb he can't tell Ashura rejecting him after 20 years? Why is he still let alive after all these 20 years?
And does it matter how many years it takes?
The justification is still plausible, he is only still alive because Kaidou wanted him as a subordinate.
Same thing with Hygoro, he worked his whole life like a slave, Kaidou has nothing to lose by leaving these guys alive, eventually they'll soften up.

If you kill him without trying to recruit him = bad, stupid villain. If you let him live and try to break the spirit at all costs = Stupid. You'll understand bro. Kaidou has nothing to lose by leaving Asura alive,he never posed a threat to him in the first place.
I think the decision to leave him alive is much better, just so it's good for the ashura to see how much Kaidou fucked up his country. Haha
