TheEnd you are right, we don't know what the daughter would have wanted. That's the problem. In a situation like this, her wishes would need to have been made very clear in some sort of legal documents, and this presumably hasn't been done if the family are going to court.
However, I think the most common reason people facing this sort of cancer treatment chose to have eggs frozen is so they themselves can use them at a later date if they choose to do so.
This is a far more unusual situation, and so you would expect that clear instructions for the use of the eggs by her parents would have been left if that's really what this poor woman wanted to happen after her death.
I suppose in this, as in many things, I believe that unless consent can be proved to have been given for the eggs to be used in this way, then we must assume that it isn't what was wanted.
I don't think most people are passing judgement on the family though. Almost everyone here has been very sympathetic towards them and the situation they are in. As a bereaved parent myself, I can empathise with the desperation this mother must be feeling, and I am truly sorry for the family.
