As much as I have read about Mr Vaknin, I have not read about the severe childhood trauma that he endured. Maybe I just didn't come across it. Do you have a link to a page which describes the trauma he suffered?
I have reason to believe my late Dad was on the Dark Spectrum, he ticks a lot of the boxes in the DSM for Dark triad, he had major trauma.
I haven't found the video where he talks in detail about his childhood trauma, but I remember that he said that his mom used to threaten to kill him frequently. I found this video, though.
