I've heard it said that umpires are necessary evil. Well, we are necessary, but we are not evil. We are hard-working and dedicated people whose primary interest is to make sure the game is played fairly. We are the integrity of the game.
Government, even in its best state, is but a necessary evil; in its worst state, an intolerable one.
It may be necessary temporarily to accept a lesser evil, but one must never label a necessary evil as good.
War may sometimes be a necessary evil. But no matter how necessary, it is always an evil, never a good. We will not learn how to live together in peace by killing each other's children.
A lot of auditions are not fun; they're just a necessary evil, and, if you're lucky, you have a few moments that are fun.
