Sesillian smirked, gloating with a twisted satisfaction as he taunted, "How about this, huh?! I have so many knights under my control that I practically have my own army! They're loyal, strong, and will do anything to protect me—even if it means being killed. They'll keep coming at you, over and over. And as long as you don't kill any of them, I'll never die!"
The knights had resilience and skill with their weapons; they wouldn't be knights otherwise. What he said wasn't wrong—without stopping them, I'd never get to him. But they chose this life, knowing full well that death was a risk. I didn't want to kill them, but maybe taking a limb or two could snap them out of this brainwashing. Limbs could always be regrown with the right healing magic.
