Macbeth Quote Analysis

Donalbain, urging his brother Malcolm to flee Scotland, warns that they are surrounded by hidden threats: even people who smile at them may be planning to kill them, and their close relatives are the most dangerous.

The metaphor 'daggers in men's smiles' collapses weapon and expression into a single image, making friendly appearances themselves into instruments of murder. The chiastic structure of the final phrase—'near in blood, / … nearer bloody'—uses sound to bind kinship ('blood' as family) and violence ('bloody' as murder) into a single inseparable idea. This parallelism enacts the collapse of trust: in a world where relatives are threats, language itself can't separate familial bonds from lethal danger, positioning the brothers to see every relationship as potentially murderous.

Support a thesis that Donalbain's line captures the play's complete breakdown of social trust—by making daggers and smiles the same thing, he announces that in Macbeth's Scotland, all social bonds have become covers for violence, and the closer someone is, the more dangerous they are.
