As written by Mr. Duncan...
Hamlet draws his general condemnation of women's fidelity from his mother Gertrude's "incestuous" marriage with the despised Claudius. I think we can assume that the Prince never cared much for his uncle, but by now he has grown to hate the man who replaced his idolized and adored father both as King and as husband to Gertrude.
The Ghost complains of "my most seeming-virtuous Queen," who fell for the blandishments of an "adulterate beast" of a brother whose "witchcraft of wit" and "traitorous gifts" stole her heart and loyalty away. Young Hamlet also takes a share in the Ghost's assessment of Claudius: a satyr in comparison with the Hyperion that was King Hamlet.
Let's examine the evidence in the play to build a character study of the late King of Denmark. Look at the Ghost's words, Horatio's dialogue with Marcellus, Hamlet's private thoughts in his first soliloquy and brief exchange with Horatio…etc. What sort of man, King, husband and father was King Hamlet?
Look then at what you know of Claudius beyond Hamlet's disdain and loathing: what qualities in him attracted Gertrude in the first place, and why? Why did she not adore King Hamlet as his son did?
This will take some thought. You might be smart to make a first entry assessing King Hamlet, then return a day later and post a comment on Gertrude and Claudius.
