Deontological ethics, mainly explained by Kant, focuses on the importance of duty and following moral rules. Although it gives a clear way to make ethical choices, it can be tough to work with when compared to other ways of thinking about morals.

1. Strict Rules: Deontological ethics often requires that we follow moral rules without any exceptions. This can create tricky situations. For example, telling the truth is usually seen as good. But what if that truth puts someone in danger? Sticking so strictly to the rules can lead to choices that feel wrong.

2. Ignoring Results: While some ethical views, like utilitarianism, care a lot about the outcomes of actions, deontological ethics might ignore how our duties affect people. This could make it seem like we lack compassion when faced with tough decisions.

3. Universal Application Issues: Kant said we should act only in ways we would want everyone else to act. However, figuring out if a rule can be applied to everyone in real life can be very complicated.

Possible Solutions:

• Contextual Thinking: This means considering the situation, where duties are balanced with what could happen as a result of our actions.
• Flexibility: We could create a mixed approach that values duty while still allowing for exceptions during unusual situations.

To sum it up, deontological ethics gives us a strong base for moral thinking, but we need to carefully think about its challenges.
