10 Count Dooku Blamed The Jedi Council For His Own Genocide
The Atrocity on Mahranee
In Christie Golden's canon novel Dark Disciple, it is revealed that Count Dooku ordered the genocide of Mahran refugees in an event that became known as the Atrocity on Mahranee. The Separatists targeted Mahranee because of its resources, plunging the world into war and chaos. The Mahran people asked the Jedi for help, and the Jedi obliged by sending in Jedi General Chubor and a clone trooper task force to assist.
Tragically, the Republic forces didn't get there in time to prevent the Separatists from destroying Mahranee's capital city. Instead, they tried to transport as many Mahrans as they could off-world. Dooku, not wanting any survivors, massacred the remaining Mahrans along with the Jedi and clones. To make it even worse, as he did so, he sent a message to the Jedi Council, telling them that the massacre was their fault since they refused to bow to him.

He was targeted by Dooku and Palpatine for his skill and potential threat. Dooku secretly planted a bomb on Grievous' ship, leaving the Kaleesh seriously injured. He then took Grievous and gave him a new cybernetic body against his will. Dooku then warped Grievous' mind until he submitted and became an agent of the Separatists, never knowing that Dooku was the one who bombed him.

5 How Count Dooku Recruited Planets To The Separatists
The Murder Of Miraj Scintel & Others
When Dooku wanted to recruit a planet to the Separatist Alliance, he would begin by acting almost charmingly. He would put on a show of diplomacy, honor, respect, and sincerity that couldn't be further from the truth. He would keep up the ruse as long as the leaders of those planets cooperated. However, if they didn't, he would have them killed and replaced with someone of his choosing. He did this to Miraj Scintel, Queen of the Zygerrian slave empire.

3 Count Dooku's Policy Towards Prisoners
Dooku The Encouraged Torture Of Captives
As the leader of the Separatist army, Dookue was the one who made and approved the policies. As a Sith Lord and Palpatine's apprentice, he believed firmly in power by any means. As such, he approved - and even encouraged - the torture of prisoners for various reasons. As with Quinlan Vos, he often both oversaw and ordered the continuous torture of captives.
2 Count Dooku Ordered The Kidnapping Of Jabba's Son
The Kidnapping Of Rotta The Hutt
In the Star Wars: The Clone Wars movie, the Republic is attempting to make a deal to travel through Hutt space. To sabotage this, Dooku orders the kidnapping of Jabba the Hutt's infant son, Rotta. He blames it on the Jedi and almost succeeds in turning the Hutts to his side before Ahsoka Tano shows up with Rotta. It was a good thing that Ahsoka got to Rotta when she did, because the boy had fallen ill during his time in captivity. Without Ahsoka, it's entirely possible that Rotta would've died - and Dooku would've blamed that on the Jedi as well.

Dooku funded a terrorist group to try to depose the rightful ruler of a peaceful world, all so that he could drag the Mandalorians into fighting for Star Wars' Separatist cause and have control of the planet and its resources.
