In the second scene of Act II of Shakespeare's "A Midsummer's Night Dream," Oberon tells Puck,
But we are spirits of another sort:
I with the morning's love have oft made sport (II,ii,404-405)
Oberon is a mischievous fairy, but he only wishes to have fun. When the mistaken identities occur, Oberon instructs Puck that they can hurry and "effect this business ere day"; that is, they can rectify the errors made by Puck in placing the nectar on the eyes of the wrong young man.
That he is not malicious is evident when Oberon tells Puck to imitate Lysander to Demetrius and Demetrius to Lysander in order to tire them so that they will not be able to duel because they are both in love with Helena. While Oberon may enjoy "What fools these mortals be!" as Puck declares, he does not want them to suffer bodily harm. So he instructs Puck to exhaust the men and correct the errors when they fall asleep. Likewise, Oberon has enjoyed his sport with Titania who has fallen in love with Bottom wearing the head of an ass, but he wishes to have her restored to her senses so he again can have his queen.
A fairy who delights in sporting with the foibles of both human and fairy, Oberon yet has a sense of fairness and even kindness, so he restores all situations to normal. His sense of fair play is in contrast to that of the mortal who do not acquire such knowledge until the end of the play.
I think that Oberon shows a degree of guilt and a desire to make reparation in the play 'A Midsummer Night's Dream' by William Shakespeare. He realises that something has gone badly wrong and wants Puck to help him fix it. In the forest, Titania relaxes with her fairies and Bottom and then gets tired. As she drowses off, Oberon is keeping an eye on her. He feels sorry for her as she sleeps innocently there and removes the charm from her eyes. When she wakes up, she can't believe her eyes when she sees who Bottom really is and what he looks and talks like. Then Theseus comes across the four of them while out hunting in the forest. They all wake up and follow him to the court. Bottom awakes too and goes off to look for his own friends.
I suppose you would say that the emotion is sympathy, perhaps. What I think he is showing is that he cares what is going on in the hearts of the mortals who are in the forest.
The way he shows this is by caring who is in love with whom. Oberon knows that Hermia and Lysander are supposed to be in love with each other. When he finds out that Puck's love potion has made Demetrius fall in love with Hermia, he is unhappy. He does not want the "wrong" people to be in love with each other.
So he sends Puck to find Helena and he himself tries to help fix the mistake. By doing this, he shows that he cares about the people's emotions.
