Every day, people undergo operations and sometimes experience unexpected and unwanted results. The story, Flowers for Algernon, is exactly like that. In this story, a 37-year-old man, named Charlie Gordon, has a mental disability and participates in an operation/experiment to increase his knowledge. After taking part in the operation, Charlie's intellect gradually reaches the status of genius. Charlie, the man who had an IQ of 68, was slowly maturing mentally and began to see the world with a completely new perspective. However, towards the end of the story, his brain regresses back to where it started. Charlie should not have taken part in the operation: he began to see the world in a different perspective, experienced unexpected results, and the operation changed Charlie's entire personality. Charlie would have been better off if he had not undergone the operation and participated in the experiment. For starters, as Charlie matured mentally, he began to see the world in a completely new way. After the operation, Charlie lost his positive outlook on life. He was oblivious to most of the negative things in life because, being a mentally challenged person, they think laughing is laughing and arguing is arguing but they never know why. He was so oblivious because he couldn't deduce the emotions of different people. Charlie also began to understand that there is a difference between laughing and mocking. Before, Charlie always thought his “friends” always laughed with him, now that he understands human nature and sees the cruelty of our world; he realizes that his "friends" were actually laughing at him. After seeing a mentally challenged dishwasher at a local restaurant drop dishes and make a mess, he saw people... in the middle of a sheet of paper... As his intelligence advances, Charlie becomes aggressive and hostile after realizing how he was taken for granted. He can no longer tolerate his former colleagues, because he still remembers the humiliation he suffered from them. His friends at the factory are threatened by his new personality and growing intelligence, and demand that he be fired from the factory. This led to Charlie becoming isolated and reclusive. Once he became a genius, Charlie became a little arrogant and even selfish. This, in turn, makes him lose his friends and all the happiness in his simple life. Since his progress reports are written from the first point of view, you can deduce how his personality has changed from amiable to hostile. Ultimately, he hopes that someone will continue and fix the mistake in Dr. Nemur and Strauss' experiment. From this it can be concluded that what he writes is the truth.
