If according to the existing evidence and legal provisions, the defendant's behavior does constitute a crime, it will be the lightest defense; Otherwise, you should not plead guilty. -The same is true of defendants in death penalty cases!
Of course, there are rare cases where lawyers think we should plead lightly.
(Non-professionals usually say guilty plea), but the defendant disagrees and must ask a lawyer to plead not guilty. At this time, the defense lawyer will generally fully communicate with the defendant and persuade the parties to defend according to their own defense plan, or after the two sides reach an agreement.
