If an action can overcome the categorical imperative, then it is a good choice. According to Kant, “The general idea behind the Categorical Imperative is that you should not act for reasons that you would not want to be universal law… so, in essence, you should not do what you would not want others to do…” (Philosophyfactory par.4 ). In other words, would you always choose the greater good over that (pull the railroad gear lever)? On the other hand, since I'm suggesting what Alex should do, (don't pull the track switch lever) choose the value of one instead of choosing to kill and end a life. The choice Alex faces involves choosing to end a life by pulling the lever of the railway switch instead of doing nothing and letting fate unfold, which would ultimately result in the train killing five people.
