i never understood Seymour's motives and it seemed that they were just forcing to hard for him to be bad, i think the game would have had more depth if he weren't bad. it seemed they wanted a big reason for yuna not to marry him to push the Yuna/Tidus stuff. i don't rate X to be honest and i feel sorry for seymour he could have been so much better if they didn't force him as a bady so hard
