How can the hadiths that deny repentance for the intentional killer of a believer—such as "Allah has refused to grant repentance to the killer of a believer" and "Every sin Allah may forgive, except for one who dies a polytheist, or a believer who intentionally kills a believer"—be reconciled with the texts from the Quran and Sunnah that affirm repentance for the killer?

The majority of scholars reconcile the hadiths and the verse in Surat An-Nisa by interpreting the verse as an emphasis on the gravity of the sin, and they affirm the acceptance of the killer's repentance, just like any other sinner. They cite as evidence the Almighty's saying: "Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills," and the hadith (definition) of the Israelite who killed ninety-nine souls, then completed one hundred and repented. If repentance was accepted for those before this Ummah, then it is even more fitting for Muslims.
