Been heavily debating whether to include a particular plot point in episode II.
Insane cloned Jedi created by the enemy seems like an intriguing concept and could lead to a ton of great battles, though I wouldn't necessarily make them Dark Jedi, just crazy. So much so that the use of them is a disaster and severely weakens the Mandalorian coalition (along with another major act in the film). More or less I don't really want any true users of the dark side of the Force except for eventually Palpatine and Vader. I can easily fit it into the plot, but I'm still unsure about it at the moment.
