A new idea for ERAM!Angel

Up until now I have been thinking sbout ERAM!Angel in areally convoluted way but I think this new interpretation is more sensible.

ERAM is the Angel and is crucial to the Prophecy. However, they did not write it. Gaster did. ERAM, However is given ownership of the Prophecy. The thing is that ERAM is not satisfied with the Prophecy because it results in them being banished so they want to subvert it. This is why they end up wanting the Weird Route as seen in the Sword Route.

I don't know if I will switch over from my pre-existing interpretation to this one but I think I will keep this a secondary theory to believe in.
