About her actions and words then, no one, no one at all, is saying they aren't appalling.
What I'm trying to say is that if you take a toddler with some degree of FAS and other natal brain disadvantages, to the slaughterhouse, let her see animals she loves being killed and disemboweled in front of her, rape her, beat her, threaten to kill her pets (after she's seen other animals killed), beat her some more, give her zero stability, rape her some more, beat her some more ...... let her watch her only decent human being die of cancer .... rape and beat her some more, let everyone who does this walk around around her without punishment, are we really surprised that she turns out to think that beating and killing is normal?.
She never really had a chance. Literally, if you know anything about ACES and formation of the brain, her brain was changed and affected from before birth to adulthood.
The only way to stop more Christas, for absolutely every single person's benefit, is early intervention. Instead the US doesn't care and the UK has cut Social Service aid to well below any effective level.
