What is the core principle of deontological ethics?

The core principle of deontological ethics is that actions are right or wrong based on adherence to duties or rules. This ethical framework emphasizes that certain actions are intrinsically moral or immoral, regardless of their consequences. In deontological ethics, it is the intention and adherence to moral duties and rules that determine the ethical value of an action.

For instance, telling the truth is considered a moral obligation in deontological ethics, even if it may lead to negative outcomes. This focus on duty and moral rules distinguishes deontological ethics from consequentialist theories, which evaluate actions primarily based on their outcomes. Thus, the emphasis on adherence to established moral principles is fundamental to understanding deontological ethics, making it the correct choice in this context.
