Query on the plot of "suicide note" at the beginning and end of butterfly effect 1.

[1] A: That's a way to put the climax or ending of the movie at the beginning. As the first floor said, it's a bit like flashback in literature. The movie really started after the suicide note, and the protagonist's mother sent him to school.

[2] A: The previous understanding is correct, but the ending is not what you said.

Sample. The ending of the film is: the protagonist keeps going back to the past through his diary to try to change the present, but the situation is getting worse and worse, so the protagonist watches the video of his birth in the hospital, travels through time and space with his super power, and returns to the moment when his mother is about to give birth to him, and ends his life in his mother's stomach ..... so he dies before he is born, and he doesn't exist in this world, so Kelly won't know him and Kelly won't die.

[3] A: "By the time I read it, I may be dead." Maybe when someone reads this letter, his plan may have been successful, that is, he may have died. What a profound sentence! But in fact, if he died, there would be no such letter and no one would read it. He just wrote this sentence from the objective fact of his birth.

[4] A: I appreciate this movie, too, but I suggest you not watch the second and third movies, which are far from the first one.
