Why did Mr. Sloper kill his nephew?
The movie did not give a clear answer to the question of why Mr. Sloan killed his eldest nephew, but it could be analyzed from the plot of the movie. In the movie, Mr. Lu was the adoptive father of his eldest nephew. He lived with his adoptive parents. However, there were some contradictions and misunderstandings between Mr. Lu and his adoptive parents, which led to Mr. Lu's dissatisfaction with his adoptive parents and some conflicts with his eldest nephew. During an argument, Mr. Lu lost control and killed his eldest nephew. Although the movie did not clearly explain the reason why Mr. Lu killed his eldest nephew, we can guess that it might be because the conflict between Mr. Lu and his adoptive parents intensified, and the death of his eldest nephew stimulated Mr. Lu, causing him to lose control and make the decision to kill. In addition, it might be because Mr. Lu felt that his nephew's existence threatened his status and interests, so he did not hesitate to die to protect his status and interests. It should be noted that this is only our guess based on the plot of the movie. The details of the plot may be different due to review and modification.
