Who's excusing and/or justifying evil? Some of us seem to understand that the woman did an evil deed...beyond comprehension, in fact. But she was not an evil person...she was crazy!
Do you really think a sane, mean woman could kill her kids? I don't.
Evil women are like Joan "Mommie Dearest" Crawford.
It takes a crazy mother to kill her kids.
Oh, please. Susan Smith was perfectly “sane”. She was also selfish and evil.
Crazy does not justify evil. She was of sound enough mind to do some meticulous planning. You are simply refusing th acknowledge evil of that depth can exist.
