Dooku knew he was not powerful enough to take on Sidious on his own. Hence his offer to Obi-Wan.
Dooku understood that he would never be powerful enough to defeat Palpatine. Here's what Dooku thought in the Revenge of the Sith Novelization said. Palpatine was an event horizon. Beneath his entirely ordinary appearance was an absolute, perfect, nothingness.
Because Count Dooku was in disbelief that Chancellor Palpatine/Darth Sidious had ordered Anakin to kill him.
To give a quick answer, Dooku didn't reveal Palpatine because he was still a loyal Sith apprentice and wanted to be a part of Palpatine's vision for the future. Dooku wanted to be his second in command and was willing to put his life on the line to manifest that.
How Count Dooku Planned to Betray Palpatine Before Star Wars: Revenge of the Sith. For his short time as a Sith, Count Dooku was well aware of Star Wars' Rule of Two. In fact, he even planned on replacing Palpatine before Order 66.
Bottom line, Dooku never considered himself a Sith. And he wasn't; he was a man looking to change the galaxy in a way the Jedi were unwilling to try. And that is why he joined the Sith and became Darth Sidious' apprentice, Darth Tyrannus. When Dooku became Sidious's apprentice, he was already an elderly man.
Anakin regrets this decision, and Palpatine reasons with him saying that Dooku was too dangerous.
Palpatine knew that the only way for Anakin to defeat Dooku was by tapping into the dark side of the Force. If Anakin did this he would surpass Dooku and carry out the rule of two, also Dooku was much older than his master Palpatine and didn't have the potential to defeat him and become the Sith master but Anankin did.
Fandom. Question: Did Maul know Sidious was Palpatine? In legends he did. In the darth plagueis novel I'm pretty sure there's a part where maul was reflecting on his master's political machinations and how he is publicly known as palpatine.
In legends, Dooku actually explains why he hates Anakin: He could feel Yoda's touch still lingering on the edges like a distant echo. Vividly his mind went back to their last meeting, on Geonosis: swords drawn at last, and finally equal.
Dooku Wanted to Destroy the Sith and the Jedi with Obi-Wan
But Obi-Wan was resolute in his belief that the Jedi were dedicated to good deeds, with honorable members who were neither corrupt nor greedy.
Dooku's fall from grace has left Yoda seriously disappointed as he felt Dooku had been lost to the Dark Side and redemption is lost when he had numerous Jedi killed in Geonosis while kickstarting the Clone Wars to boot.
When Dooku left the Jedi Order to become a Sith Lord, Yoda thought he merely left rather than turned to the Dark Side. Dark side clouded jedi orders ability to sense things properly. Also yoda did not believe dooku was a Sith lord.
Sidious was well trained from his own Master, Darth Plagueis, in disguising, hiding his Force abilities and Force signature to the point that Jedi could not pinpoint the Dark Side of the Force that definitely should have been radiating off of him.
When Count Dooku kidnapped Palpatine, did he know that Palpatine was Sidious himself? Indeed he did. Dooku (aka Darth Tyrannus) knew his master's identity.
Put simply, he wasn't powerful enough. It wasn;t some blunder on Yoda's part, or some brilliant move by Sidious. Here's what the Revenge of the Sith Novelization said on the topic. Finally, he saw the truth.
Amedda was one of the few beings in the galaxy who knew Palpatine's secrets, most notably his true identity as a Sith Lord.
The showdown on Coruscant was a confrontation that took place in the Supreme Chancellor's Suite of the Galactic Senate in 19 BBY. It began after Jedi Knight Anakin Skywalker informed Master Mace Windu that Supreme Chancellor Palpatine had revealed his identity as a Sith Lord to him.
Yoda Was Warned About Order 66 At The Beginning Of The Clone Wars - But Why Did He Ignore It? Star Wars revealed that Yoda received a warning about Order 66 at the start of the Clone Wars, making it unclear why the Jedi Master chose to ignore it.
This is confirmed later in the movie when Obi-Wan informs Padme that Anakin killed them. Both are torn apart with hurt and confusion, trying to make sense of something so terrible.
Obi Wan was unable to defeat Count Dooku because the Count was a significantly better lightsaber duelist. Obi Wan was a master in Form III lightsaber combat. Form III is an almost entirely defensive style of combat. Obi Wan was essentially a diplomat before the Clone Wars.
The canonical comic Star Wars: Darth Vader #7 confirms the younglings' deaths caused Anakin grief, self-loathing, hatred and pain, fueling his descent even further into the dark side.
In Star Wars canon, there are currently only four younglings that are known to have survived the infamous Order 66 and Darth Vader's slaughter, while in Legends, there are 20 known survivors.
Anakin and Obi-Wan board Grievous' ship, the Invisible Hand, and confront Dooku, who knocks Obi-Wan unconscious, leaving Anakin to face the Sith Lord alone. Anakin gives in to his hatred of Dooku and uses his anger to overpower him, severing both of Dooku's hands and leaving him helpless.
Anakin Skywalker
During that battle, he learned why Qui-Gon supported and defended Anakin, when he showed how strong his connection to the Force is. Dooku had very little respect for the young Jedi Knight, despite his bravery and unbelievably strong connection to the Force.
