"chance(155)
may crown me..."See in text(Act I - Scene III)
Allowing chance the ability to crown Macbeth is an example of personification, or giving human characteristics to non-human or non-living things. Ascribing such qualities to things like fate and death are fairly common devices in literature.
This is an example of personification, attributing human qualities to non-human or abstract things, in which the act of Murder is portrayed as a thin and ghostlike man.
