No one person has the right to withhold knowledge from another. No one is wise enough. - Stephen R. Donaldson

It was clear to all there gathered that power is a dreadful thing, and that knowledge of power dims the seeing of the wise.

Power was dreadful and treacherous. When it was not great enough to accomplish its wielder’s desires, it turned against the hands which held it.

Do not hurt where holding is enough;
do not wound where hurting is enough;
do not maim where wounding is enough;
and kill not where maiming is enough;
the greatest warrior is he who does not need to kill.
