But people may do great good accidentally, though with evil intentions - conversely people may do great evil though having the best of intentions.

There was no more dangerous kind of madman than one who devoted a good brain and a courageous heart to unhealthy ambitions.

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.

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.

Evil cannot and will not be vanquished by evil. Dark will only swallow dark and deepen. The good and the light are the keenest weapons.

One that confounds good and evil is an enemy to good.
