Much of life we are faced by choices we'd not like to have in an ideal world. That's tough. Complaints can be registered with your nearest priest.

The state spending money on a handicapped child is depriving the aid to others. Others will die who would have lived.

Others will argue that it is irrisponsible. That is of course their right to do so. If they want to set up a charity to help provide that's fine.

If they chose not to have an abortion of course they chose to have the child! Merely that this is not a choice they wished to face changes nothing. If you're religious take it up with a priest. Personally I think it's a cruel universe and merely squealing that it's not fair changes nothing.
