Keep in mind this isn't your God.

This one was born like the rest of us. Imagine him more like a king or dictator so controlling he has to take over every land or destroy it trying.

In the Realm of our birth we had an area to rule over, but there were also common areas. As The Brat gained in power his soldiers patrolled those areas and could accuse anyone at their own leisure without any evidence.

He was systematically eliminating the other deities to rise in power.
