I understand that the question you raised is about whether liability can be ignored without causing harm. From an ethical point of view, responsibility is not limited to whether actual harm has been caused. Even if there are no obvious negative consequences, a person may still have to bear the following responsibilities： 1. Ethical responsibility: based on our behavioral intent and decision-making process 2. Role responsibilities: based on our position or commitment in society 3. Responsibility for prevention: to avoid possible injuries 4. Caring responsibility: active attention to the well-being of others For example, a person driving drunk but fortunately did not hit anyone. Although it did not cause actual injury, it still violated legal and moral responsibilities because the behavior itself was potentially dangerous. The core of responsibility lies in how we treat our own behavioral choices and their potential impact on others, not just whether harm is ultimately caused.
