The power to do good is also the power to do harm; those who control the power today may not tomorrow; and, more important, what one man regards as good, another may regard as harm.

So long as a man’s power, that is, his capacity to realize what he has in mind, is bound to the goal, to the work, to the calling, it is, considered in itself, neither good nor evil, it is only a suitable or unsuitable instrument. But as soon as this bond with the goal is broken off or loosened, and the man ceases to think of power as the capacity to do something, but thinks of it as a possession, that is, thinks of power in itself, then his power, being cut off and self-satisfied, is evil; it is power withdrawn from responsibility, power which betrays the spirit, power in itself.

. . .It is the Law that while Evil, unopposed, may accomplish terrible deeds, the power of Good can never be overthrown when opposed to Evil. . .

A good end cannot sanctify evil means; nor must we ever do evil that good may come of it.

For he that does good, having the unlimited power to do evil, deserves praise not only for the good which he performs, but for the evil which he forbears.

Good can exist without evil whereas evil cannot exist without good.

“In innocence there is no strength against evil,” said Sparrowhawk, a little wryly. “But there is strength in it for good.”

For good people to do evil doesn’t require only religion, or even any religion, but simply one of its key elements: belief without evidence—in other words, faith. And that kind of faith is seen not just in religion, but in any authoritarian ideology that puts dogma above truth and frowns on dissent.

Much that may seem evil can be good.

How can someone have the freedom to choose and the power to act freely, unless he were able to be evil, should he so wish?

He that does good, having the unlimited power to do evil, deserves praise not only for the good which he performs, but for the evil which he forbears.

I don't think that you have any insight whatsoever into your capacity for good until you have some well-developed insight into your capacity for evil.

If we kill those who are evil, we will become evil ourselves; we will be killers. If we attempt to deal with evil by destroying it, we will also end up destroying ourselves, spiritually if not physically. Evil can be defeated by goodness. Evil can be conquered only by love. We must somehow be both tolerant and intolerant, accepting and demanding, strict and flexible. An almost godlike compassion is required.

you need power only to do something harmful.otherwise love is enough,compassion is enough.
