Lydia, why do you think you have the right to tell a bereaved mother that she must continue living? Surely that is her choice, and should not be dependent on your religious view of life?
Had my daughters died in dreadful circumstances, none of your compassionate people would have made the slightest difference to MY decision.
I have no desire or need to force you to do anything that makes you unhappy. I merely ask you to show the same humility - it is not your place to decide whether somebody can be comforted or not.
As for taking tissue and organs from a dead child, that was clumsily done and nobody has defended it, but I am sure if the parents had been approached in a proper fashion they would have agreed, as they would want to help in the search for cures or treatment for disease.
I really think you need to stop dragging in irrelevant issues.
