"There is a 5%–10% lifetime risk of suicide in persons with schizophrenia. Suicide is defined as a self-inflicted death with evidence of an intention to end one’s life. The NT recounts Jesus’ awareness that people intended to kill him and his taking steps to avoid peril until the time at which he permitted his apprehension. In advance, he explained to his followers the necessity of his death as prelude for his return (Matthew 16:21–28; Mark 8:31; John 16:16–28). If this occurred in the manner described, then Jesus appears to have deliberately placed himself in circumstances wherein he anticipated his execution. Although schizophrenia is associated with an increased risk of suicide, this would not be a typical case. The more common mood-disorder accompaniments of suicide, such as depression, hopelessness, and social isolation, were not present, but other risk factors, such as age and male gender, were present."
