The phrase "un deviating" implies a sense of steadfastness, consistency, and resoluteness. To convey the opposite meaning of this term, one might consider antonyms such as unsteady, wavering, inconsistent, erratic, unpredictable, or capricious. These words suggest a lack of stability, reliability, or adherence to a particular course of action. They connote a sense of ambiguity, vacillation, or impulsiveness, which is fundamentally at odds with the idea of remaining unchanging or unwavering in the face of adversity. Thus, by considering the antonyms of "un deviating," one can gain a more nuanced understanding of its meaning in the broader context of communication and semantics.
