Answer and Explanation:
"Hamlet" was written by Shkespeare and tells the story of how Prince Hamlet seeks to avenge the death of his father, King Hamlet, who was murdered by his own brother, Claudius.
Prince Hamlet, although determined to avenge his father's death and even after learning that his uncle, Claudius, was the murderer, finds himself very confused and undecided on how he should promote this revenge. This indecision makes him miss out on very beneficial opportunities to achieve his goals.
Hamlet, is as confused as melancholy, has instability and doesn't know how to act. He is contemplating and structuring endless plans that are never put into practice, and he spends a lot of time rambling on philosophical issues.
This type of behavior causes Hamlet to be seen as someone troubled and that causes many problems all around him. Amid his indecision to get revenge on his uncle, he ends up causing problems to his mother, his kingdom, his friends, his fiancée and even himself, while his uncle remains free and unpunished for his brother's murder.
