undeterrable
Impossible to dissuade
Undeterrable describes someone or something that cannot be discouraged or turned aside from a course of action.
Where deterrence fails, the undeterrable person persists: She was undeterrable in her pursuit of justice.
The word often appears in security contexts discussing threats that conventional deterrence cannot prevent.
