Just to satisfy your need for an imature post: OMG!!!!!!!!!11 1 DAT PLOT WAS THE SHIZNIT YO!

Anyway...

While the plot of Berserk is definitely great, I have to disagree with your reasoning. Guts does not swing his sword for love, he swings it because it is the only time that he feels complete. He may fight for the love of his comrades (not just Caska) but he sings his sword for himself.
