“True evil can indeed be defeated, but it can never be completely eradicated. Even if you destroy every dark soul that comes your way, others will rise up to replace them.”

“...I once thought I defeated the evil in my heart. I learned something: We can face our demons, burn them up, stomp them into the ground. I turned mine to ashes. But even if you destroy the evidence of evil, you can't heal your heart. Not by yourself.”

“When you love someone completely, you'll do anything to protect them, even if you sacrifice your soul. Because if you don't, you destroy your soul anyway.”

“You may encounter many defeats, but you must not be defeated. In fact, it may be necessary to encounter the defeats, so you can know who you are, what you can rise from, how you can still come out of it.”

“How do you defeat an army that regenerates? For every demon you kill, one of your fallen gives birth to a replacement. Almost instantaneously, shadow demons rise from the corpses to reinforce the Dark Army. Still we fight on – and fight we must, or all is for nothing.”

“What do you do when there is an evil you cannot defeat by just means? Do you stain your hands with evil to destroy evil? Or do you remain steadfastly just and righteous even if it means surrendering to evil?”
