Seifer was bent on power and was willing to do whatever he needed to get it. he lost his was and squall remained ture and focused! they were rivals and were equal in states through most of the game. but the one thing that stood out to me is that seifer trained and fought constantly to beat squall an pushed himself to his limit to become powerful. Squall became powerful on his own accord and still managed to beat seifer. Seifer wanted to win more than Squall to prove himself, yet Squall fought knowing that he had to win for what he knew was right.
