Sometimes the defense of lawyers may well excuse the killers and harm public morals, but their "perfect" legal services are correct. Because the law of the rule of law is neutral, it transcends morality; and the "equal confrontation" proceedings must be Ensuring that the defendant enjoys all the legal services he has purchased. Even if the defendant is really a murderer, the lawyer helped him win the case and be released, and justice is frustrated. From the long-term interests of the legal system or "rule of procedure", it is still worth it. It can be outside the case. What is the correct understanding of this passage? ['The rule of law and morality are antagonistic.', 'Justice cannot be found in a single case.', 'The significance of maintaining legal procedures is more than just justice.', 'To ensure the implementation of legal procedures, lawyers often have to do it.']
