The Shakespearean tragedy Macbeth is a play about the lengths one will go to satisfy his or her ambition and the consequences of one's desire (etext found here).
The thane of Fife had a wife: where is she now?--
What, will these hands ne'er be clean?--No more o'
that, my lord, no more o' that: you mar all with
this starting.
Canst thou not minister to a mind diseased,
Pluck from the memory a rooted sorrow,
Raze out the written troubles of the brain
And with some sweet oblivious antidote
Cleanse the stuff'd bosom of that perilous stuff
Which weighs upon the heart?
a remedy that stops or controls the effects of a poison
Canst thou not minister to a mind diseased,
Pluck from the memory a rooted sorrow,
Raze out the written troubles of the brain
And with some sweet oblivious antidote
Cleanse the stuff'd bosom of that perilous stuff
Which weighs upon the heart?
If thou couldst, doctor, cast
The water of my land, find her disease,
And purge it to a sound and pristine health,
I would applaud thee to the very echo,
That should applaud again.
If thy speech be sooth,
I care not if thou dost for me as much.
I pull in resolution, and begin
To doubt the equivocation of the fiend
That lies like truth.
