Sometimes life comes along and knocks down your tree

Just as the title states, sometimes life just comes along and knocks down half of your tree.  It's been a relatively dry summer with very few storms, so the jury is still out on why this branch decided to fall off.  I suppose this just confirms my decision to cut the whole tree down.  I just realized that it is a crab apple tree and it's apparent that a great deal of it is dying.  The branches on the backside look like they could be mayhem for my fence if they start falling.
