I would argue that the main issue is Max's fanatic work ethic and slightly cynic personality.
Less so her powers as Deus has banged more than one Super.

Also uncertain regarding the bit about being able to kill Deus outright.
As far as we know any nut with a gun can do that. Its why Deus is carefull to keep the conflict in the area where he has superiosity.
The realm of words and oppinions. Instead of getting a blue battlesuit to duke it out with Max xD
