The only issue that will arrive is:

1. Gods gains Worshippers of their Domain by acting in accordance with their powers. That means Hum will gain Death worshippers as he accepts the dead into his realm and would lose them if he resurrects people.

2. He would gain Life Worshippers as he resurrects people.

It almost guarantees a situation where Hum can possibly have access to one of his Major powers, but never both—given his two domains are at odds with one another.
