That's an option. Yamajii did blame Mayuri for killing all those Rukongai-located souls without applying for permission or explain his reasons. Mayuri could have simply pointed out that the need of doing so to restore the balance of souls wouldn't have been there at all if Yamajii didn't fail to kill Yhwach 1000 years ago, so that basically it was Yamajii's fault.
