In general, the central purpose of writing a causal analysis essay is to show both, the causes as well as effects of a certain topic or the aspect. The code of conduct in this essay is "why" which is to be answered or a casual analysis. However, the conclusive aim of such an essay is to either come up with a casual argument, challenge a claim, or prove any point that is deemed a widely held belief. So, generally, a causal analysis essay can help to analyze and evaluate the events that can either impact human life or have the ability to shape human life. It is more or less an analysis essay.
