How does Puck`s interference in the play affect what happens?

Puck is a symbol of nature. He loves tricks and pranks and leading the unsuspecting or unwary into precarious situations. Although he is officially a servant of Oberon, Puck is most often seen acting independently and is not an ordinary part of the fairy retinue. Even when following orders, he according to his own interpretation of what he has been told.

As a result, like blind Cupid, Puck acts blindly with the juice that he has been instructed to use in Act II, Scene I. Oberon has given vague instructions about a man in Athenian clothing, which will confuse Puck's perception of the man he is meant to find. Puck is playing the role of "Cupid painted blind," through the flower that cupid's arrow has painted purple. The result of hia confusion is hilarious.
