Human reason can excuse any evil.

Knowledge is power. Power to do evil...or power to do good. Power itself is not evil. So knowledge itself is not evil.

Because inside me is a beast that snarls, and growls, and strains toward freedom.. and as hard as I try, I cannot kill it.

I think we cry to release the animal parts of us without losing our humanity. Because
inside me is a beast that snarls, and growls, and strains toward freedom, toward Tobias, and, above

Man has been reared by his errors: first he never saw himself other than imperfectly, second he attributed to himself imaginary qualities, third he felt himself in a false order of rank with animal and nature, fourth he continually invented new tables of values and for a time took each of them to be eternal and unconditional...If one deducts the effect of these four errors, one has also deducted away humanity, humaneness, and 'human dignity'.

I know there’s evil in the world, and there always has been. But you don’t need to believe in Satan or demons to explain it. Human beings are perfectly capable of evil all by themselves.
