I didn't think anybody had suggested that the perpetrator was a 'victim', sorry if I missed FranticFrankie's posts when I said upthread that there was nothing but condemnation here.
If you wind back far enough through the history of violent people, there are often points where they went wrong/things around them went wrong.
I agree that for this young woman, it was being fed the lie that she could become a man, and possibly the effects of testosterone on a female body.
The extent of her cruelty and violence suggests that she might have been a nasty piece of work even without the testosterone.
It would be good if she was rehabilitated in prison, when she is off the testosterone - rehabilitated, not 'getting a taste of her own medicine', prison officers have enough to deal with without punishment beatings by prisoners.
There was only one victim in this case: the woman she terrified and assaulted.
