Is there a limit to how complicated the train dilemma can get? When at one point does the question become trivial? (The train dilemma I'm referring to is the popular flip the switch to save 5 people but kill 1?)
The train dilemma or the trolley problem is a thought experiment used to explore ethical decision making and the moral principles involved in such situations. There is no limit to how complex the scenario can get as the goal is to provoke thought and discussion, rather than to find a definitive answer.

However, the complexity of the scenario may lead to different interpretations and possible outcomes, so it can become challenging to reach a clear conclusion. The question can become trivial when it becomes a purely hypothetical scenario without any real-world implications, or when the information provided is not sufficient to make a decision. The answer to this type of dilemma is subjective and dependent on one's personal values, ethics, and beliefs.
What if I hypothetically had no morals or ethics?
