Revenge

Anyone and everyone, at one point in their lives, has had thoughts or even carried out plans of revenge. Don't deny it, you have too. Revenge is everywhere, even if it only exists in your head. When i hear revenge, I think payback, or karma or anything along the lines of getting back at someone for something they have done to you. As far as I believe, it's just human nature to have that feeling of wanting to get back at someone who has upset you or caused problems for you in your life. So even if you'd like to say that you've never wanted revenge on someone, I'm sure that you have at least seen it occur from an outside point of view either in books, T.V shows, or watching others carry out their revenge. One example that is very popular especially most teenage girls is the television show Pretty Little Liars, and another is the famous playwright of Shakespeare's Hamlet.

In Pretty Little Liars, five high school girls were all best friends until one night one of them, Alison, went missing and and was later found dead. For the next few years, the other four girls continue to seek the killer and find new things and details about the murder every day. They discover a team of people who were against Alison, and do the best that they can to get more information and plan a revenge on making their lives miserable and stressful. Someone, or multiple people, that go by "A" have constantly been antagonizing the girls and everyone else in the town, and trying to place the blame of the murder on other people. The girls want nothing more than to get revenge on this person/people and will do whatever they can to try and achieve that, even if it means making sacrifices and losing friendships or relationships in their lives. However, before Alison's death, she constantly took advantage of others, manipulated people, and bullied anyone who she thought had a lower social status than she did. The "A Team" is still trying to get revenge on Alison, but doing it by torturing her friends and putting them in dangerous and mysterious situations. This T.V show has a  twisted plot line, with a ton of revenge included and displayed throughout the episodes as the series goes on. In multiple of the episodes, Alison's ghost makes appearances in her friends lives at random times and tries to communicate and tell them things such as to hints or clues of information that could be useful.

Creepy, but still interestingly, Pretty Little Liars isn't the only media that has a ghost return and make interactions with the characters. In Shakespeare's Hamlet, the ghost of Hamlet's father appears, and reveals that it was Hamlet's own uncle, Claudius, who has killed him and he must seek revenge.Claudius, soon after his brother's death, marries Hamlet's mother and makes Hamlet go mad with his planning of revenge. During his struggles to get back at his uncle, he accidentally kills the father of Laertes, Polonius, causing more problems to come his way. Now not only King Claudius wants to also get revenge on Hamlet, but Laertes does also. This play is filled with revenge around every corner of every page, and that is what helps us readers to find the reading to be enjoyable and exciting, because revenge creates an interesting story, making it easier for people like me to actually get into the story and feel more involved and curious to what is going to happen next.
