ONE possibility? A person has an inborn instinct to live. If he was playing football, he was somewhat healthy.
What does killing the mother of his child have to do with any ailment 'you' put forth as his defense?
"The thief/satan has come to KILL/Rob/Destroy"!
First of all I'm not "defending" him.If you read my posts you'll see that I've put forth everything from "scumbag" to brain injury/disease...and one or two things in between...as possible *explanations*,not defenses.And as for him being "somewhat healthy" it's possible that his heart,lungs,muscles and spine were healthy but his *brain* was not.
And you are correct to observe that people have an inborn instinct to live,that "instinct" residing in the brain.But remember,the heart has an inborn "instinct" to beat in a particular manner.But as you very probably know it doesn't always do so.I,for example,know it from personal experience.
