I have to disagree here. Meetra may have gotten an..undignified death but at least she died herself and she even went all Obi-wan and helped Revan and the republic after her death. Revan got mind screwed for hundreds of years and only got out of it not being dead or broken by the Emperor because of Meetra's help, just so he can be turned crazy, attempt to commit genocide, and then be killed by his captives. I think his death is way worse. =/
I agree about T3's death though..I really didn't see it coming. I mean..did the Emperor really need to vaporize him?
