Writing a composition killed my parents, just to make the composition miserable, make it touching and get a higher score, so my parents died and this work was produced.

Even if you want to get high marks by writing touching stories, you won't write your parents to death. What you did is wrong, but from your point of view, you want to get high marks, and there is nothing wrong with it. But from your parents' point of view, it's just another form of curse … apologize to your parents.
