Food for thought...
Things that happened TO Sauron, meaning he couldn't have planned or had control over those events:
I'd realised he was Sauron from the first instant, so I've really enjoyed seeing how the writers have both dropped hints about the truth, had him saying lines with double meanings all the time and portrayed him manipulating people, without trying to tip their hands to obviously to the audience. It's quite the tightrope they've walked. So I've viewed his every action from that perspective.
[*]Getting shipwrecked...
[*]...trapped on a raft...
[*]and almost eaten by a sea worm (twice)
[*]Meeting Galadriel in the middle of the ocean
I assumed from the first appearance that the sea monster was some evil creature in his power and he was never really one of the passengers to begin with. He might've joined them in the confusion after the first attack on the ship.
(Much like what happens with the similarly named Dr. Tolian Soran in 'Star Trek Generations', when he appears aboard the Enterprise-B with the rest of the real survivors from the "shipwrecked" Lakul.)
He quickly separated himself from the others on the raft, so the others could be killed by it but not him. The instant they're all dead and it's just him and Galadriel, the creature magically disappears and never comes back.
[*]Getting rescued by the Numenoreans (more precisely the father of the guy who much later would take his ring)
He encourages Galadriel to go to sail in the direction of Numenor doesn't he? Then presumably summons the summoned the sudden titanic storm to blow them there. Again the instant the storm disappears, they are in Numenor waters.
[*]Galadriel refused to believe that he stole that symbol from a dead man, as he told her numerous times
[*]Galadriel insisting that he was a king, while he told her he wasn't
Those fall into the category of tricking her to believe those things. She assumes he's lying about those things because he's afraid of his destiny, he cleverly allows her to believe this, by ironically telling her the truth. The more he told her the truth, the more she believed her own wrong assumptions. I thought it was great writing.
Surely that was a direct result of him trying to join the smithy guild (for ring smithing purposes) but having to brutally murder the guild members, when they attack him, for which he is caught.
[*]Galadriel somehow convincing the Numenorians to send ships to Middle-Earth
I'm a bit hazy on this one without a rewatch but him tricking Galadriel into thinking he was the king of the southlands was in part behind her argument to go there. The Numenorians only take note of him because he's let Galadriel think believe he is worth taking note of.
[*]Getting caught in the eruption of Mount Doom
[*]Stabbed by an Orc...
[*]...resulting in an infected gut wound
Didn't that happen off screen and so is dubious if it was true.
[*]Galadriel taking him to Eregion (basically the strong hold of his worst enemies)
[*]Getting cared for by the best Elven healers, who somehow don't sense he's Maiar (= a semi-divine supernatural being)
I'd imagined the wound was a ruse to get taken there. In the books I believe Sauron is amongst the Elves for centuries (I think?) and they don't suspect. I think he have to accept that he can conceal his true nature.
[*]Celebrimbor letting him assist in a project he couldn't have had any knowledge of prior
Like in LotR, he has spies everywhere. It's not difficult to imagine he'd be aware of it. Having said that, there are a few points in the series where we see him react to events and change tack.
Sauron didn't lie to Galadriel. He didn't kill her when he had the chance (twice). He even gave Galadriel her brother's dagger back after it was taken from her (twice). He gave Celebrimbor the solution to allowing his "enemies" to be saved.
The first part is because she was used by him to manipulate events. It's a key bit of LotR lore that Sauron wanted the Elves and co to have rings, so he could rule over them with his one ring. It says something like when the Elves realised they'd been deceived, they hid the three rings and didn't use them.
I thought Sauron was supposed to be manipulative, cunning, seductive, deceitful and all that evil stuff.
He very much was for me.
