I think the 'incarnation' (it's not really that) of
evil spirits is far more taxing than the 'incarnation' of the
Valar and good
Maiar. There is a quote around this forum somewhere to the effect that
Morgoth spent his immense native power in domination of others, so that only "Morgoth + minions" had the same original power as the
Melkor who once fought the Valar by himself. The bad guys spend power in domination, so they are -- far -- less powerful when killed, and this means they have more difficulties (or perhaps are completely prevented if they are weak) in creating a new body. On the other hand, they leave their 'testimony' in the form of bad
creatures and fear.
What reason is there to think that aside from
Sauron's Ring, anyone other than Morgoth let their power go out into the world around?
Here's some about Morgoth you might have been refering to.
Quotes from Myth's transformed in Morgoth's Ring.
But Melkor had already progressed some way towards becoming 'the Morgoth' a tyrant (or central tyranny and will), + his agents. Only the total contained
the old power of the complete Melkor; so that if 'the Morgoth' could be reached or temporarily seperated from him agents he was much more nearly controllable and on a power level with the Valar.
To gain dominion over
Arda, Morgoth had let most of his being pass into the physical constituents of the Earth - hence all things that were born on Earth and lived on and by it, beast or
plants or incarnate spirits, were liable to be 'stained'.
Melkor 'incarnated' himself (as Morgoth) permanently. He did this so as to control the hroa, the 'flesh' or physical matter of Arda. He attempted to identify himseld with it.
Thus, outside
the Blessed Realm, all 'matter' was likely to have a 'Melkor ingredient'. and those who had bodies, nourisged by the hroa of Arda, had as it were a tendency, small or great, towards Melkor: they were none of them wholly free of him in their incarnate form, and their bodies had an effect upon their spirits.
But in this way Morgoth lost (or exchanges, or transmitted) the greater part of his original 'angelic' powers, of mind and spirit, while gaining a terrible grip upon the physical world
Here's from Osanwe-Kenta, essay published in the
Vinyar Tengwar #39.
Here
Pengolodh adds a long note on the use of hroar by the Valar. In brief he says that though in origin a "self-arraying", it may tend to approach the state of "incarnation", especially with the lesser members of that order (the Maiar). "It is said that the longer and the more the same hroa is used, the greater is the bond of habit, and the less do the 'self-arrayed' desire to leave it. As raiment may soon cease to be adornment, and becomes (as is said in the tongues of both
Elves and
Men) a 'habit', a customary garb. Or if among Elves and Men it be worn to mitigate heat or cold, it soon makes the clad body less able to endure these things when naked".
There's more about it in there too. It is said by Pengolodh that the more a spirit uses a rament to do things necessary to the life of a body, such as eating, or begetting, it will become dependant upon the ramient, as an incarnate. But is also goes on to say that
Melian is the only known of case of this, and it does not seem only to refer to begetting when it says this. Now, I'm not sure what to make of that really. It could be she was the only case where a
Maia become as an incarnate just out of doing those things, eating, drinking, and whatnot, versus listening to music, rather than those evil ones who may have become as an incarnate just from a desire to be, as was the case with Morgoth. It is not necessary to bodily form that one kill or torture others, but it seems doing things things will have the same result.
But here you have a large part of the text that I used in my
balrog speculation above. The other major part being where it is said why Morgoth can come back but Sauron cannot and that is given in quotes in the post I liked to above.
