Samuel understood at last why this being hated men and women so much: he hated them because they were so like himself, because the worst of the was mirrored in them. He was the source of all that was bad in men and women, but he had none of the greatness, and none of the grace, of which human beings were capable, so that by only by corrupting them was his own pain diminished, and thus his existence made more tolerable.

No matter how hard Evil tries, it can never quite match up to the power of Good, because Evil is ultimately self-destructive. Evil may set out to corrupt others, but in the process corrupts itself.

And I told him that I believed in God because I had seen His opposite. I had seen all that He was not, and been touched by it, and so I could no more deny the possibility of an ultimate goodness to set against such depravity than I could deny that daylight followed darkness, and night the day.

After all, evil was a kind of poison, an infection of the soul.

You cannot perform acts of evil in the name of a greater good, because the good suffers. It is corrupted by what has been done in its name.

It has always seemed to me that there are two types of people in this world: those rendered impotent by the sheer weight of evil it contains, and who refuse to act because they see no point, and those who choose their battles and fight them to the end, as they understand that to do nothing is definitely worse than to do something and fail. --The Collector

No matter how hard Evil tries, it can never quite match up to the power of Good, because Evil is ultimately self-destructive. Evil may set out to corrupt others, but in the process corrupts itself. That's just the way Evil is. All things considered, it's better to be on the side of Good, even if Evil occasionally has nicer uniforms.

Evil, unlike good, is constantly at war with those most like itself, and ambition is its spur.

After all this time, he had hope, and then hope was gone, and he hates himself for giving in to hope. He, who exists only to kill the hopes of others, could not destroy the hope within himself.
