Is it an accomplice for a lawyer to defend himself knowing that he is guilty?

Naturally, I can't understand it this way. Criminal defense system has a history of thousands of years, and it is of course reasonable for it to be accepted by modern countries. First, the whole social system is a complex organism. If the judicial system only has the prosecution power of the procuratorate and the judicial power of the court, but does not give the defendant the right of defense and lawyer, it will inevitably lead to some unjust, false and wrong cases. In order to avoid these unjust, false and wrong cases as much as possible and ensure the defendant's full right to defense, it is a historically tested method. Although it will increase the difficulty of convicting defendants and even let some defendants escape some sanctions, modern society ruled by law thinks this is an acceptable price. Second, from the individual point of view, lawyers' professional ethics is higher than ordinary social ethics. This is the same as the doctor's. Doctors can't refuse treatment just because the injured are criminals. This is the same. Civilization has reached this point, and all punishments for criminal acts must go through legal procedures.
