Will the suspect get a heavier sentence if he doesn't hire a lawyer?

Legal subjectivity:

Just because a suspect doesn't hire a lawyer doesn't mean he will be convicted of a felony. Because people's courts make criminal judgments based on facts, laws and legal evidence. The responsibility of defenders is to safeguard the litigation rights and other legitimate rights and interests of criminal suspects and defendants according to facts and laws. If a criminal suspect meets the conditions for legal aid, the legal aid institution shall appoint a lawyer to defend him.

Legal objectivity:

Article 6 of the Criminal Procedure Law The people's courts, people's procuratorates and public security organs must rely on the masses, take facts as the basis and take the law as the criterion in criminal proceedings. All citizens are equal in applying the law and are not allowed to have any privileges before the law. Article 35 If a criminal suspect or defendant fails to appoint a defender due to financial difficulties or other reasons, he or his near relatives may apply to a legal aid institution. To meet the conditions of legal aid, legal aid institutions shall appoint lawyers to defend them. Article 37 The duty of a defender is to present materials and opinions on whether a criminal suspect or defendant is innocent, light or relieved of criminal responsibility according to facts and laws, and to safeguard the litigation rights and other legitimate rights and interests of the criminal suspect or defendant.
