#2 Blurring the bloodline

Promoting is in the McMahon blood. Vince’s grandfather promoted mostly boxing, and his father famously headed what would become WWE before Vince took over and took the company national, and then worldwide. Stephanie and to a lesser extent Shane are waiting in the next generation, but Triple H appears to be the one positioned to take over booking, thus ending McMahon bloodline’s leadership over the product.
Of course, Helmsley has married into the McMahon family, and though his real legal last name remains Levesque, he is for all intents and purposes, a McMahon now. Nonetheless Vince is nothing if not a man of principle, and it is conceivable that, against all cooler heads and logics, he may still have some misgivings about permanently giving up his life’s work to someone only related to him by marriage.
