Final answer:
A signed confession does not need to include a reason for the commission of the crime as long as it contains an acknowledgment of wrongdoing and relevant details such as dates and amounts of loss. The primary legal focus is on the awareness and voluntary waiver of rights before confessing.
Step-by-step explanation:
A signed confession does not necessarily require a reason for the commission of the crime. The confession must contain an acknowledgement that the confessor knew the act committed was wrong and should also include the dates of the offenses and the amount of loss if applicable. However, providing a motive or reason for the crime is not a legal requisite for a confession to be considered valid in court. This is reflected in landmark cases such as Miranda v. Arizona where the focus was primarily on whether the defendant was aware of their rights and had voluntarily waived them before confessing.
