Savior complex
In psychology, a savior complex is an attitude and demeanor in which a person believes they are responsible for assisting other people. A person with a savior complex will often experience empathic episodes and commit to impulsive decisions such as volunteering, donating, or advocating for a cause. A person with the complex will usually make an attempt to assist or continue to assist even if they are not helpful or are detrimental to the situation, others, or themselves. It is often associated with other disorders, such as schizophrenia and bipolar disorder, and is commonly used interchangeably with the similar term 'Messiah complex'.
