She deliberately accused non-existend people of rape, for the purpose of avoiding being confined in detox. She had no intention of those accusations particularly hurting anyone (since it's impossible to hurt people who don't exist) nor any fear of anyone countering the accusations (since non-existent people can't fight back).
It was only Nifong et al. got involved that her accusations changed to point to real people. And given the transcripts of the photo ID session there's a pretty clear causal relationship.
I don't care if she accused 'little green men', if she hadn't made the accusation Nifong wouldn't be involved. She is just as guilty.
