I think it is apt for the cirsumstances the daughters are living. The parent who is in no condition to bear the upbring of his two disabled daughters should be allowed to die a dignified death. No government aid or human assistance is anticipated in this case hence he should be permitted to have them die tleast he will be freed from the financial burden as well as mental torture of witnessing the apple of his eyes deteriorating in such a state.
Even the Almighty would pardon him in this case! God Bless!
