Demetrius is a very amorous person with a volatile character. He has a wonderful upbringing; he is respected by Hermia’s father and his closest friends. However, Lysander does not trust him, suspecting him of duplicity. Despite his inconstancy, Demetrius shows an enviable persistence in achieving the love of Hermia, trying to win over her father. But he truly deserves our reproaches for his attitude to the former lover, Helena. He even threatens to leave her at the mercy of wild animals, if she does not stop chasing him. Demetrius easily plays with human feelings, although he does not forget about his own spiritual anguish. He neglects the destinies of others in trying to achieve own happiness. In the image of Demetrius embodied selfish, accustomed to receiving whatever he wants, by any methods.
