Impenitent

lit., "without change of mind" (a, negative, metanoeo, "to change one's mind," meta, signifying "change," nous, "the mind"), is used in Rom 2:5, "impenitent" (or "unrepentant"). Moulton and Milligan show from the papyri writings that the word is also used "in a Passive sense, 'not affected by change of mind,' like ametameletos in Rom 11:29," "without repentance."
