In deontology, are the consequences of an action relevant in determining its ethical value?

In deontology, the consequences of an action are generally considered irrelevant in determining its ethical value. Deontology, also known as duty-based ethics, is a moral philosophy that emphasizes the importance of following rules, principles, or duties, regardless of the outcome. According to deontological ethics, the rightness or wrongness of an action is determined by whether it adheres to these moral obligations, not by whether it produces good or bad consequences. For example, a deontologist might argue that lying is always wrong, even if it would lead to a positive outcome. The ethical value of the action depends on its adherence to the principle of honesty, not on its consequences. This contrasts with consequentialist ethical theories, such as utilitarianism, which judge the morality of an action based solely on its outcome. Deontologists believe that certain actions are inherently right or wrong, regardless of their effects. While deontologists may consider the potential consequences of an action when deciding how to apply a moral rule in a specific situation, the consequences themselves do not determine the action's fundamental ethical value. Rather, the ethical evaluation rests primarily on the adherence to the established duties or principles.
