The ghost of Hamlet's father is disgusted by Claudius' deceitful acts. The ghost believes that Claudius used the "witchcraft of his wit" and his "traitorous gifts" (traitorous abilities) to seduce and win "The will of my most seeming-virtuous queen." (Lines 43-46) Therefore, the ghost knows that the queen was seduced, and has married Claudius because she has been tricked into doing so. The ghost instructs Hamlet to not think ill of the queen: "nor let thy soul contrive/Against thy mother aught." (lines 85-86) The ghost wants the queen's judgement to be left to Heaven.
