Why can't angel god beat shura god?

I can't determine the concrete result of the battle between the angel god and the shura god, because these two characters may belong to different fictional works or worldviews. However, if we set the hypothetical background of this question as a specific fictional world or work, then the reasons why the angel god can't defeat the shura god may be as follows:

1. The shura god may have more powerful power or skills. In some world views, shura gods may be portrayed as more powerful and fighting gods, so they may have more obvious advantages in fighting.

2. Angels may be limited by factors such as the power of belief. In some stories, the power of faith can affect the power and performance of God. If the belief of angel gods is relatively weak, it may lead them to be at a disadvantage in the battle with shura gods.

3. Angels may face other limitations or weaknesses. For example, they may be bound by some kind of curse, seal or boundary, which may weaken their strength and combat effectiveness.

It should be noted that these reasons may not apply to all fictional works or worldviews. Therefore, to answer this question accurately, we need more background information and specific fictional world settings.
