I think that this is not a good outcome for the tree. This is because the tree had shown extreme levels of selflessness to give away every part of the tree to the boy. The boy kept taking from the tree and not giving his time to the tree as the boy had kept growing. I think that sacrificing her trunk is a sign that the tree is especially good. This is because the tree had shown signs of selflessness and there had not been any signs of selfishness shown by the tree. This implies that the boy should have learned to be selfless like the tree and not selfish as he had grown up.
