[A Balrog of Morgoth]

The first reason of the fall of Rome is the MORALLY fall.

Oddly enough, Rome declined as Christianity took hold. Rome at the height of its power was ridiculously decadent.

I believe you must look elsewhere for an explanation of the fall of Rome.

I don’t find it odd. Given a religious monopoly (rather than a polytheistic model such as existed in pre-christian Rome and Greece), there is great incentive on behalf of its leaders to gather as many resources as possible to reinforce their position. And because these institutions produce nothing and are not taxed on the wealth they accrue, goods and services that would otherwise be available to the public are not. The effect is that the church eventually controls the public’s purse strings and supersedes government, and when government and church become one, the result is a parasitocracy which cannot sustain itself; the host dies.
