A Final Fantasy Trivia Question!

I have a little final fantasy trivia question that I came about and had NO idea what the answer was! If you could post the answer here I would be eternally greatful!

Which character (in one of the Final Fantasy games) realised he had not much time left in life and wanted to destroy life and everything in it?

Please help!

I think it was Kuja. Garland said that Kuja didn't have long to live on the 3rd Disc in Terra. I also remember Kuja saying something along the lines of 'If im not allowed to live then no-one else should be allowed to either.'.

And you know the whole crystal ending was a bit of a giveaway with that :P
