Is the oppressor who dies after having oppressed one stronger than him considered among the people of Hellfire or the people of Paradise?

Injustice is forbidden, and its perpetrator is threatened with severe punishment. Allah Almighty says: "Indeed, the curse of Allah is upon the wrongdoers," and He says: "And never think that Allah is unaware of what the wrongdoers do." It has been reported in the Hadith: "Injustice will be darknesses on the Day of Resurrection." However, if an unjust person dies as a monotheist and has not repented, then their matter is subject to the will of Allah; if He wills, He will punish them, and if He wills, He will forgive them, and people will take their rights from them. It is not permissible to judge anyone from the people of the Qiblah as being in Hellfire or Paradise except by news from Allah and His Messenger, and this matter ceased with the death of the Messenger of Allah, peace and blessings be upon him.
