Hlabangwane avoided making eye contact in the packed court and looked down throughout proceedings.
Angry Soweto residents said they want him to be released on bail so they can “deal with him”.
Mandla Dube, who attended court as a concerned resident, said he would like to see Hlabangwane plead guilty and not waste the court's time.
Hlabangwane was arrested after his partner allegedly discovered human body parts in his fridge at his home in Protea Glen after he went shopping.
Police spokesperson Brig Brenda Muridili said an off-duty police officer living in the area responded to the crime scene.
After the gruesome discovery, Hlabangwane stabbed himself in an alleged suicide attempt and was admitted to hospital.
