He has been acting malicious lately. It's no longer just him being a smug prick, but actually encouraging a psychopath mass killer Devil to turn one of humanity's best Devil Hunters (who already freed him and his organization from the blight of another Horseman) into a weapon, which we now know Yoru would use to turn Earth into a giant battlefield for eternity.
Either way he is atleast maliciously stupid (sort of like Miri) and probably needs to be removed before he causes more harm.
