Green Lights, Yellow Cars and Church Steeples

The green light at the end of the pier in front of Daisy's house represented Gatsby's dream that he was trying to reach for. At the end of the story, "Gatsby believed in the green light, the orgastic future that year by year recedes before us. It eluded us then, but that’s no matter—tomorrow we will run faster, stretch out our arms farther. . . . And one fine morning——So we beat on, boats against the current, borne back ceaselessly into the past." I think that F. Scott Fitzgerald is saying that we are always going to be striving for a dream in our lives, and that dream often is influenced by our lingering feelings toward the past. Even though we often focus too much on our past and tell ourselves time after time that some thing should be left in the past, it affects us. But we still move forward against obstacles because eventually, we have to move on and let our past be our past. Daisy was Gatsby's past and Gatsby's objective was to resume their lives 5 years ago and pretend that nothing has changed, but that wasn't possible. Gatsby's obsession with the past between him and Daisy was what got him killed.
Gatsby's yellow car was significant because that instigated the game changer, causing Myrtle's death. Even though Daisy was driving, it was Gatsby's car that physically hit Myrtle and no one knew that Daisy was driving except for Gatsby and  Nick. From Nick narration, we know that Tom knew it was Gatsby's car who hit Myrtle, so when Wilson, distraught and hung up on revenge, approached Tom, Tom told Wilson that it was Gatsby who owned that yellow car and who had killed Myrtle. From this information, Wilson probably also assumed that Gatsby was the one that was having an affair with Myrtle because he knew that Myrtle ran out to try to talk to someone in the car, which was how she got hit. Needing to justify Myrtle's death, Wilson shot and killed Gatsby and then himself. As for the church steeple, “There was nothing to look at from under the tree except Gatsby’s enormous house, so I stared at it, like Kant at his church steeple, for half an hour.” Kant was a philosopher that debated and emphasized morality and honest, and said that lying was always morally wrong. Because Nick is now involved in Daisy and Gatsby’s relationship, he is now in a dilemma deciding whether or not he should tell the truth about the knowledge that he knows about both Daisy & Gatsby and Tom & Myrtle. Especially since Nick said that he was one of the only honest people he ever met, he is conflicted about what kind of role he should play in this situation. On the other hand, Nick was raised learning to remain objective and keep his opinions to himself in any situation, therefore he wouldn't be honest since he doesn't say what he actually believes and retains judgement. This was exactly what he did as his role in the sticky situation between the rest of the characters and as a result, Gatsby and Myrtle were both killed. If Nick had made a difference in the affairs of his friends, we don't exactly know if it wouldn't prevented these deaths, but we're convinced that it would've changed the outcome of this story.
