How does artemidorus’ role in act 3.1 reflect the theme of fate

On the day of the prophecy Caesar sees Artemidorus and tells him that the prophecy is false but the soothsayer replies that the day is not over yet.  He tries to give Caesar a letter but was prevented by Decius.  The soothsayer reflects fate in a sense that he is always there to remind Caesar and though he tries to help him, factors come into play that makes Caesar’s death inevitable.

the tone of the passage is sympathetic to the forbidden love of romeo and juliet. the nurse plays a significant role in the play. she is responsible for making their meeting again possible. additionally, there is a sense of warning in the choice of words of the nurse. she seems to be authoritative when she calls romeo "scurvy knave", and at the same time the fact that she addresses to him as "sir" reflects respect. the nurse is "vexed", this word describes her confused state of mind. on the one hand, she finds romeo a fine and eloquent man, but on the other, it is thought that man's nature forces men to try to trick women.
