What is Hamlet's attitude towards women?
Hamlet doesn't trust women. He says that they are two-faced and never say what they mean. The best description of his attitude toward women can bee seen when he is talking to Ophelia:
"God hath given you one face, and you make yourselves another. You jig, you amble, and you lisp, and nickname God's creatures, and make your wantonness your ignorance. Go to, I'll no more on't. It hath made me mad. I say we will have no more marriages. Those that are married already --all but one-- shall live. The rest shall keep as they are. To a nunnery, go" (Hamlet 3.1.142-148).
Clearly, he is traumatized by what his mother did to his father (betrayal/murder) and is through with women. He believes that if his mother could do something so horrible, then every woman is capable of such trechery. Any feelings he may have had for Ophelia are dubious, now and he tells her to go be a nun and never get married.
Perhaps the best one-line summation of Hamlet's attitude towards women is where he concludes an early soliloquy with the words: "Frailty, thy name is woman!" (Act 1, Scene 1, line 146) He has come to this conclusion because of his mother's infidelity to her death husband. He thinks she married Claudius, not because she was wicked, but because she was weak and therefore easily persuaded. Something very similar takes place very early in Shakespeare's Richard III. Richard approaches the widow of the king he has just murdered and persuades her to consider marrying him while she is still walking in her dead husband's funeral procession.
