All that is necessary for the triumph of evil is for good men to do nothing. The lives of the best of us are spent in choosing between evils. The doing evil to avoid an evil cannot be good. This is the course of every evil deed, that, propagating still it brings forth evil. Both appear great at a distance, but when we approach them we find they are far less insurmountable than we had conceived.
Evil is inevitable, but is also remediable.
Evil has no substance of its own, but is only the defect, excess, perversion, or corruption of that which has substance. The true rule in determining to embrace or reject anything is not whether it have any evil in it, but whether it have more of evil than of good. There are few things wholly evil or wholly good. Men never do evil so completely and cheerfully as when they do it from religious conviction. There are a thousand hacking at the branches of evil to one who is striking at the root.
