The 'Karen' thing is yet another American import. And, as with most American political & cultural imports, it doesn't work in the UK.
I read a piece recently, maybe by Julie Birchill, about how Karen is a working class name in the UK which was popular the 1960s (it was), but the American 'Karen' is a middle class 'Get me the manager' pushy person. So - not the same, doesn't have the same connotations.
Of course White blames others. It's his modus vivendi. The women he raped probably brought it upon themselves in his estimation.
Why do they use that photo of him? There's a far more accurate one available.
