Why does pain exist?  Is it to teach us lessons?  Help us to survive?  Is it a defense mechanism used by our sense of self-preservation?  That’s generally the accepted theory.  We evolved pain to help us survive, because we are wired to avoid that which causes us pain. 

What doesn’t make sense to me is that some pains are so deep that they make you wish you were dead.

How did we evolve that as a survival trait?  The wish to not survive?  Is it just bad programming?

When this pain hits animals, I guess they just lay down and die.  Some humans do the same.  The ones who survive use their human intellect to circumvent the bad biological programming and carry on despite the overwhelming pain.

Thank God for intellect.
