Final answer:
If a play has an evil villain who evokes negative emotions from the audience, it is likely a tragedy.
Step-by-step explanation:
If you attend a play and it has an evil, evil villain who is so bad that you want to hiss "Boo" at him as he sets his sights on a pure heroine, you are probably watching a tragedy.
Tragedy is a genre of theater that often features a villainous character who causes harm to the protagonist or the people around them. The villain in a tragedy is typically morally flawed and may be responsible for the downfall of the hero or heroine. In addition, the villain in a tragedy often elicits negative emotions from the audience, such as fear, pity, or anger.
An example of a tragedy with an evil villain would be William Shakespeare's play Macbeth. In this play, the character of Macbeth is driven by his ambition and commits various evil deeds in order to gain power. As a result, the audience may feel compelled to hiss or boo at Macbeth during the performance.
