in macbeth,by william shakespear-what quotes are relate to murder

This play is chalked full of quotes on murder. Here are just a few:

And pall thee in the dunnest smoke of hell,
That my keen knife see not the wound it makes,
Nor heaven peep through the blanket of the dark,
To cry ‘Hold, hold!’

Yet who would have thought the old man to have had so much blood in him?

If it were done when ’tis done, then ’twere well
It were done quickly. If th’assassination
Could trammel up the consequence,
