What is the theme of wicked?

The musical Wicked tells the story of the witches of Oz, Elphaba and Glinda, and their friendship and rivalry. The theme of the musical is that people are not always what they seem, and that good and evil are not always what they appear to be. Elphaba is a powerful witch who is misunderstood and feared by everyone in Oz, but she is actually a kind and compassionate person. Glinda is a beautiful and popular witch who seems to have everything, but she is actually insecure and lonely. The musical shows that people should not judge others based on their appearance or their reputation, and that everyone has the potential for both good and evil.
