The Second Rule is that the greatest harm can result from the best intentions. It sounds a paradox, but kindness and good intentions can be an insidious path to destruction. Sometimes doing what seems right is wrong, and can cause harm. The only counter to it is knowledge, wisdom, forethought, and understanding the First Rule. Even then, that is not always enough. [...] Good intentions, being kind, can encourage the lazy, and motivate sound minds to become indolent. The more help you give them, the more help they need. As long as your kindness is open-ended, they never gain discipline, dignity, or self-reliance. Your kindness impoverishes their humanity.
The above words are spoken by Nathan Rahl in Stone of Tears, the second book in Terry Goodkinds Sword of Truth series.
