Does impersonation heighten the evil of an immoral behaviour, perhaps similarly to illegality? I tend to think of just laws doing exactly that, and suspect that impersonating, e.g. by identity theft, another (pretending to be you to steal your property or rape your wife) does something similar, and even wondered if the answer tells us something about the the law.
For some reason, I reminded of Mocnik's argument for human rights, via an enunciatory principle, but in terms of crimes against humanity, though I don't expect anyone to address that here (whether my identity being my own could be a basis of how my human rights can be violated).
