I would like to say that the poem, My Last Duchess by Robert Browning, explains its message more thoroughly and more clearly than the poem written. The Young Housewife written by William Carlos Williams,

For one, the length of Browning’s poem, My Last Duchess, allows a perfect opportunity for the author to sneak in multiple connections, and various outstretched supporting details. And using those details to create a vivid image of what’s happening in the monologue written by Robert Browning. And when you have a detailed image of the scene, the message becomes more apparent to the naked eye. “How such a glance came there; so, not the first, Are you to turn and ask thus. Sir, 'twas not, Her husband's presence only, called that spot, Of joy into the Duchess' cheek: perhaps Fra Pandolf chanced to say "Her mantle laps, Over my lady's wrist too much," or "Paint Must never hope to reproduce the faint, Half-flush that dies along her throat": such stuff Was courtesy, she thought, and cause enough, For calling up that spot of joy.” Clearly, she’s a young, very attractive young woman who’s married to the narrator – the Duke. She’s the idealistic woman of her time when it comes to the looks and poise. She has the half-flushed that dies at the neck. But she was anything but idealistic when it came to the expectations. She was a “player” and it got on her husband’s nerves with the following exempt from the poem, My Last Duchess. “She had A heart--how shall I say?--too soon made glad, Too easily impressed; she liked whate'er She looked on, and her looks went everywhere. Sir, 'twas all one! My favour at her breast, The dropping of the daylight in the West, The bough of cherries some officious fool, Broke in the orchard for her, the white mule, She rode with round the terrace--all and each, Would draw from her alike the approving speech, Or blush, at least. She thanked men,--good! but thanked, Somehow--I know not how--as if she ranked” She had a heart, meaning a heart for a romance other than the romance with her husband – if there ever was one.

One thing is the fact he killed her. How he killed her is questionable. All that says is, “This grew; I gave commands; Then all smiles stopped together. There she stands, As if alive.” He gave commands, meaning he probably paid a “for hire” murderer and had her killed. It says. “Then all smiles stopped together.” She stopped smiling in the face of death, and her smiling stopped altogether. The biggest evidence was this, “The Count your master's known munificence, Is ample warrant that no just pretence, Of mine for dowry will be disallowed; Though his fair daughter's self, as I avowed, At starting, is my object.” The Duke, the narrator, is talking about how he has planned another wedding with the daughter of the guest’s master. He called his new fiancée “my object” and that’s a big clue how he thinks of his newly acclaimed fiancée.

The message, I think, is men consider women nothing more than an object – a collectable item. They “pick up” a girl and once they lose interest in them, they’re either forgotten or left on the street. And in case, he had her killed by someone. The details narrow down the number of different interpretations and focuses on the message everyone will conclude upon.
