[Star Wars: The Clone Wars] Why is Count Dooku so evil?

In Attack of the Clones he explains his reasoning for becoming a Separatist. And while he's morally questionable, his actions are understandable.

But by the time of Clone Wars he's a loathsome, despicable human being that's irredeemable.  

Why the sudden contrast?

A brilliant debater who can give you a hundred convincing reasons why it's OK to smoke crack is still going to get addicted if he actually does it.

You could have let the dark side get inside you for the best reasons in the galaxy, but then it sets up shop in your heart and soul and remodels them to suit itself. Once Dooku went beyond political idealism to actually choosing the quick and easy path... having convincing arguments at his command just made him the most persuasive junkie in the crack house.

Just say no to the dark side of the Force.
