obdurate
Refusing all persuasion
Obdurate means stubbornly refusing to change one's mind or course of action, even in the face of persuasion or pressure.
The word carries a sense of hardness—someone obdurate is unmoved by appeals to reason or emotion: The obdurate landlord refused to negotiate despite the tenants' pleas.
It often implies a moral judgment that the stubbornness is unreasonable or cruel.
