Throughout the initial phase of the movie, Heinrich's behavior showcased his inner turmoil. He was known for his quick temper, often lashing out at his close associate, Sigfried, and the members of his expedition team. This short temper reflected his internal battles and frustrations.
He grappled with a lack of purpose and fulfillment in his life. Despite achieving academic and professional success, he felt an emptiness that could not be filled by his accomplishments. This internal struggle is what ultimately led him to embark on the perilous journey to Tibet, hoping to find answers to his existential questions and attain a deeper meaning to his existence.
