hubris -
Excessive pride, presumption or arrogance originally toward the gods.
Wikipedia
Hubris (due to the hypercorrection of the Greek spelling due to the incorrect transcription of /u/ for /ὕ/) means extreme haughtiness or arrogance. Hubris often indicates being out of touch with reality and overestimating one's own competence or capabilities, especially for people in positions of power. Hubris appears in the terms "act of hubris," and "hubristic.".
