Read the excerpt from act 3, scene 4 of The Tragedy of Macbeth.First Murderer. Ay, my good lord; safe in a ditch he bides,With twenty trenched gashes on his head;The least a death to nature.

“Twenty trenched gashes” describes many deep, severe wounds. The First Murderer emphasizes their violence by saying even the least wound would be enough to cause death. So “brutal” best matches the description; “quick” does not describe the wounds themselves.
