Why would Killerbee give up Samehada?

[Bad Touch Yakushi]

Plot

Samehada chooses who is allowed to wield it, I doubt it would willingly give up a chakra source like the hatchibi just to go with some kisame wig wearing looking motherfucker

See post above.

 

[Reviewing Logic]

likely post the shinobi war the cloud agreed to give back Samehada in order to add to the shinobi nations peace treaty

i can see why Bee would give it up, but i have yet to see why Samehada accepted Shizuma since the latter's plan practically hinges on Kagura joining him.
