Here is the finishing paragraph of a recent post on Field of Merit site.
….when we ask for merit to be given to a partcular person who is suffering, we are not making any judgment as to what the outcome should be. The purpose of offering merit is to support the person to accept difficult circumstances, to live, sometimes to die, skilfully within them, and for the compassion of the universe to find expression.
