But if Antonin succeeded, she might have been safe for a little while. Safe until he decided that she was too big of a threat. One cannot remain in power long without looking out for their own Brutus constantly over their shoulder. Antonin had every reason to fear that she would turn on him at some point.

It wouldn't be a stretch to imagine that he would get rid of her when he had the chance before she could make trouble for him.
