I think it's because I cannot imagine for one second holding any living being under water until they drowned, let alone my own child, that i think she can only have been beyond any fom of rational controlled human mentality.
But I don't know - and anyway, none of that means I feel 'sympathy' for her. But if we just say 'evil - beginning and end of it' then we might miss a trick in our understanding of how to prevent horrific killings by people who have, in a sense, already issued a signal that all is not well. After all, if the child had been adopted, she would be alive today.
I was chilled by JH, but in the end, if someone says they can't cope - for whatever reason, justified or otherwise, in our opinion, then forcing them to accept, cope, is in no-one's interest...and is tantamount to saying "well if you can't cope, you must be evil to want to get rid of your own child, so as punishment you will be forced to keep her, not have her adopted, and that'll teach you!"
