My preference, Virtue Ethics with a strong thread of Deontology.

FYI. I had to ask ChatGPT for definitions.

Deontology, consequentialism, and virtue ethics are three prominent normative ethical theories that propose different criteria for what makes actions morally right or wrong:

1. **Deontology**: This theory argues that the morality of an action should be based on whether that action itself is right or wrong under a series of rules, rather than based on the consequences of the action. It emphasizes the importance of duty and rules. A well-known deontologist, Immanuel Kant, argued that we should act according to maxims that we would want to become universal laws.

2. **Consequentialism**: This theory asserts that the morality of an action is contingent on the action's outcome or result. The right action is the one that produces the best consequences. The most famous form of consequentialism is utilitarianism, which suggests that actions are right if they promote happiness or pleasure, and wrong if they promote unhappiness or pain.

3. **Virtue Ethics**: This approach focuses on the inherent character of a person rather than on specific actions. According to virtue ethics, morality is about building good character traits, such as kindness, honesty, and courage. Actions are not evaluated in isolation but as part of a life lived well. This theory is associated with the ancient Greek philosopher Aristotle, who emphasized the importance of developing virtuous habits.

Each of these theories provides a different perspective on ethics and is used in moral philosophy to analyze various moral dilemmas and questions.
