"How does that make me any better than the Black Star or any of the lost cities we've destroyed in the past?" Solus asked.
"For starters, you are not picking on innocents." Lith replied. "These people are scum and there's no doubt about it. On top of that, you'd not use their lives to sustain yours. For that, I'm more than enough.
"You'd use their lives in self-defense just like with the Tree. The next time we face a deadly enemy and you get seriously injured, the Bleed might save us. Each one of these bastards is like an extra life for you.
"If you get hurt, the tower won't drain me in the middle of the fight to save you. If we ever get separated again, you'd have the means to find me and fight on your own instead of bleeding energy with each passing second."
Solus couldn't deny the truth of those words but it wasn't enough to placate her conscience. Lith gave her time to mull over her options before talking again.
