If the cause be not good ...

"But if the cause be not good, the king himself hath
a heavy reckoning to make, when all those legs and
arms and heads, chopped off in battle, shall join
together at the latter day and cry all 'We died at
such a place;' some swearing, some crying for a
surgeon, some upon their wives left poor behind
them, some upon the debts they owe, some upon their
children rawly left. I am afeard there are few die
well that die in a battle; for how can they
charitably dispose of any thing, when blood is their
argument? Now, if these men do not die well, it
will be a black matter for the king that led them to
it; whom to disobey were against all proportion of
subjection."

Henry V, Act 4, Scene 1
