You really think you're gonna win a fight like this without taking any lives? Finish them off properly! That's how you show respect to the enemy who started this battle.

No man's life is worth more than another! If you're gonna put your life on the line, you do it as equals! I don't care if you're brothers, or master and apprentice, or whatever! You should only die for a guy who'd die for you! There's nothing honorable about throwing your life away as though it's nothing! That's just showing off like a kid!

Cut the flattery. You can stop your admiration. It's only natural to show our true levels of Reiatsu. Whether it is worthy of praise is something you will learn after you die.
