idolize
To admire someone so much you think they are perfect.
To idolize someone means to admire them so intensely that you see them as almost perfect, ignoring their flaws and limitations. When you idolize a person, you put them on a pedestal, treating them more like a hero from mythology than a real human being.
Young fans might idolize a famous athlete, memorizing every statistic about their career and defending them fiercely against any criticism. A student might idolize a teacher so much that they copy their mannerisms and hang on every word. The problem with idolizing people is that everyone has weaknesses and makes mistakes. When you discover that your idol is imperfect, you might feel shocked or betrayed, even though they were always just human.
You can deeply admire someone without idolizing them. The difference is recognizing their humanity while still respecting their achievements. A basketball player who studies LeBron James's technique without idolizing him can learn from both his successes and his mistakes. That kind of clear-eyed admiration helps you grow, while idolizing can leave you disappointed when reality doesn't match your impossible expectations.
