Ahmed Best, who played Jar Jar Binks in the Prequel Trilogy, says he wanted his character to die in Revenge of the Sith (at 45:33):
“I always complained to George, like when I realized that Sith was not gonna have Jar Jar in it pretty much and they were moving very very far away from me… I always complained to George that I didn’t get a good death. I wanted to really be just hacked to pieces in some kind of way, and George wouldn’t do it.
The interesting thing about Jar Jar is everybody keeps looking for an explanation for him, which is human nature, and I’m gonna have a big part of my book talking about why this is what it it because I thought a lot about it. And I like all of these theories that try to explain the reasoning for Jar Jar. We talked about the dark Jar Jar before and this one [in the novel Aftermath: Empire’s End] where he becomes this tragic character who realizes he’s been manipulated in his mind. Everybody’s trying to come up with this reasoning. Everybody’s trying to come up with a finality for him. I think it’s cool and interesting.”
