Is it permissible for the guardian appointed by the judge to oversee the rights of a minor to pardon the killer in cases of intentional homicide?

If the minor is solely entitled to the blood-money, his guardian may consider what is more beneficial for him: retribution (qisas) or blood-money (diyah). If he deems retribution more beneficial, he should exact it from the perpetrator. If he deems taking the full blood-money more beneficial, he should take it. It is not permissible for the guardian to settle for less than the full blood-money if the perpetrator is well-off (wealthy). However, if the perpetrator is in straitened circumstances, it is permissible for the guardian to settle for less than the blood-money. It is a condition for the one who pardons (al-aafi) to be an adult and of sound mind, so the pardon of a child or an insane person is not valid. The guardian may settle for the full blood-money if the perpetrator is well-off, or for less than the blood-money if the perpetrator is in straitened circumstances. However, he is not permitted to pardon, because it would invalidate the minor's right.
