Chronic traumatic encephalopathy (CTE) is a progressive degenerative disease found in individuals who have been subjected to multiple concussions and other forms of head injury. A variant of the condition, dementia pugilistica, is primarily associated with boxing. CTE has been most commonly found in professional athletes participating in gridiron football, ice hockey, professional wrestling and other contact sports, who have experienced head trauma, resulting in characteristic degeneration of brain tissue and the accumulation of tau protein. Individuals with Chronic Traumatic Encephalopathy may show symptoms of dementia such as memory loss, aggression, confusion and depression which may appear within months of the trauma or many decades later. --Wikipedia
I understand the Church's teaching on suicide--that taking one's own life is a sin. I understand, too, that the basis for this teaching is a solemn respect for the immeasurable value of each human life, and the belief that faith in God is sufficient to endure all trials. Suicide is always sad, but unlike the Church I cannot condemn it. I do believe in the immeasurable value of each human life, but I do not comprehend a God that would say, "Let's give Dave CTE and see how he does with it." I only hope Dave's suicide is viewed as a self-sacrifice, a last act of self-less service by a truly remarkable, successful, and gifted man.
