Actually, when I think about it like that, Sauron's plan was exactly the same as Morgoth's, only on a far smaller scale.~modoturan

Yes and No.

That is both Morgoth and Sauron were in "Absolute satanic rebellion":

But in this 'mythology' all the 'angellic' powers concerned themselves with world were capable of many degrees of error and failing between the Absolute Satanic Rebellion of Morgoth and his satellite Sauron, and the faineance of some of the other higher powers or 'gods.'~Letter 156

By "absolute satanic rebellion" I would assume that both Morgoth and Sauron opposed Eru, and they were against the Valar.

However, there is a difference between the two, and I think Iarwain was on the right track when saying Sauron's plan was smarter...maybe not smarter, but definitely wiser and more practical.

Morgoth became a nihilist, that is he believed in nothing, he solely wanted to destroy everything. The problem with that is Morgoth's goal was impossible, he essentially wanted the power that only Eru had, and that is trash everything, including everyones wills (fea). Not even the Vala had the power to destroy a person's will.

Sauron knew this was impossible, he never denied existance, he wanted to control and dominate others wills - much different than destroying everything alltogether:

"He [Sauron] still had the relics of positive purposes, that descended from the good of the nature in which he began: it had been his virtue (and therefore also the cause of his fall, and of his relapse) that he loved order and co- ordination, and disliked all confusion and wasteful friction. (It was the apparent will and power of Melkor to effect his designs quickly and masterfully that had first attracted Sauron to him.)"~Home X: Morgoth's Ring; Myths Transformed

I imagine Sauron was drawn to Morgoth in the way that Saruman was drawn to Sauron in The Lord of the Rings. Saruman does tell Gandalf about joining with Sauron, but ultimately betraying him before the end. Saruman in essense, just takes the "path of least resistance." Saruman desires to be the Dark Lord himself, and in order to achieve his desires, he thinks buttering up to Sauron - and then backstabbing him - would be the best way.

Sauron is originally drawn to Morgoth, probably because of the power and splendour of Morgoth, but also Morgoth's ability to efficiently and speedily do what he wanted. So, in this way Sauron believes to achieve his own plans (of world "domination") he take the apparent path of least resistance - following Morgoth. However, Sauron is a smart one, he recognizes Morgoth is pretty much spiralling into self-destruction, and if you want to put it this way says: "uh-uh I'm not going down on Morgoth's sinking ship." He abandons Morgoth's SS Imploder, puts on a nice face for the Maiar after Morgoth is punished, and runs to Middle-earth to start his own plans.

I don't know if Sauron ever planned to backstab Morgoth, but there is a clear difference between how they both wanted to run things. Sauron's plans ultimately were probably wiser, because his plan of control and domination was possible, Morgoth wanted to undo everything, wanted the power of Eru - not possible:

Sauron, however, inherited the 'corruption' of Arda, and only spent his (much more limited) power on the Rings; for it was the creatures of earth, in their minds and wills, that he desired to dominate. In this way, Sauron was also wiser than Melkor-Morgoth. Sauron was not a beginner of discord; and he probably knew more of the 'Music' than did Melkor, whose mind had always been filled with his own plans and devices, and gave little attention to other things.~Home X: Morgoth's Ring; Myths Transformed
