Did you feel Sorry for Seifer? (Spoilers may rise)
I did. Ok he was a villain but I feel sorry for villains in real life - I may hate them but I realize that no one is born evil so they must have been turned some how.
That's what I like about Square they make beleive able vilains they have good sides and It shows that they wern't always evil (Most of the time Exdeath was the excetion)
I think Seifer was in a sense fooled into his evil ways he wanted his dream to be real and in the end it just got too real for his own good.
Another thing I'd like to point out is that I don't think he realzied at first that he WAS the Bad guy look at some of his lines - he generally believes he's doing the right thing (At first).
