Programmed cell death (PCD) is implicated in the occurrence and development of HCC. Moreover, immune-related genes have a crucial role in cancer progression and patient prognosis. This study employed 10 clustering algorithms to conduct high-resolution molecular subtyping based on PCD-related genes, immune-related genes, microRNA, long non-coding RNA, and methylation data. Subsequently, we developed hepatocellular carcinoma consensus immune-cell death index (HICDI) by employing subtype-specific genes and merging 10 commonly used machine learning algorithms into 101 unique combination frameworks. Our HICDI score exhibited enhanced predictive ability compared to previously published HCC biomarkers. Patients with a low HICDI score exhibited higher overall survival and improved responses to immunotherapy. The high HICDI group exhibited a propensity for \u201ccold\u201d tumors marked by immune suppression and exclusion; however, drugs such as paclitaxel may present viable therapeutic options for these patients. We verified the model gene kinesin family member 2C through\n                    <jats:italic>in vitro<\/jats:italic>\n                    experiments, demonstrating its role as a potential oncogene affecting HCC progression and as a promising therapeutic target. Overall, HICDI possesses the potential for extensive applications in informing personalized treatment decisions and improving outcomes for patients with HCC.\n
