Then, when making his argument as to why he should be king, he says to Henry, "Thy hand is made to grasp a palmer's staff/And not to grace an aweful princely sceptre" (5.1.97–98). Ideas of justice are paramount throughout the play, especially the notion of where justice comes from and who determines it. This is hinted at when Thump first meets Henry, and Henry asks Gloucester's opinion. Gloucester says,   And let these have a day appointed them For single combat in convenient place, For he hath witness of his servant's malice. This is the law, and this Duke Humphrey's doom. Of this scene, Michael Hattaway has commented, "the feudal ritual of trial by combat is reduced to the grotesque fights between the drunken armourer and his apprentice [...] It serves to mirror the realities of the play: instead of seeing justice determined by God with regards to the rights of the adversaries, here we see simply a trial of might." As Henry himself says,   For by his death we do perceive his guilt. And God in justice hath revealed to us The truth and innocence of this poor fellow, Which he had thought to have murdered wrongfully. He returns to this notion later, again arguing that truth is a defence against death and defeat:   What stronger breastplate than a heart untainted? Thrice is he armed that hath his quarrel just; And he but naked, though locked up in steel, Whose conscience with injustice is corrupted. Henry believes in the purity of justice, and cannot imagine how it could possibly be corrupt; "And poise the cause in justice' equal scales/Whose beam stands sure, whose rightful cause prevails" (2.1.199–200). However, the perversion of justice is also a dominant theme throughout the play, despite Henry's inability to see it. One of the most famous lines in the play, spoken by the rebel Cade's sidekick Dick the Butcher, is "the first thing we do, let's kill all the lawyers". Whether this means that lawyers are the protectors of justice, or the agents of its corruption is disputed. Gloucester assures Eleanor that as long as he has truth on his side, his enemies cannot destroy him: "I must offend before I be attainted,/And had I twenty times so many foes,/And each of them had twenty times their power,/All these could not procure me any scathe/So long as I am loyal, true, and crimeless" (2.4.60–64).
