It is often said that mankind needs a faith if the world is to be improved. In fact, unless the faith is vigilantly and regularly checked by a sense of man's fallibility, it is likely to make the world worse. From Torquemada to Robespierre and Hitler the men who have made mankind suffer the most have been inspired to do so have been inspired to do so by a strong faith; so strong that it led them to think their crimes were acts of virtue necessary to help them achieve their aim, which was to build some sort of an ideal kingdom on earth.

Your intentions will be good. Without consideration and forethought, however, your actions could still be evil. That is the problem, of course, evil is always easy and resisting it is never so. Evil is relentless; and anyone, if they tire, if they are not vigilant, can fall prey to it.

Hell is paved with good intentions.

Most of the evil in this world is done by people with good intentions.

I hurt myself deeply, though at the time I had no idea how deeply. I should have learned many things from that experience, but when I look back on it, all I gained was one single, undeniable fact. That ultimately I am a person who can do evil. I never consciously tried to hurt anyone, yet good intentions notwithstanding, when necessity demanded, I could become completely self-centred, even cruel. I was the kind of person who could, using some plausible excuse, inflict on a person I cared for a wound that would never heal.

Fate has a twisted sense of humor.
