Everyone deserves compassion. I feel sorry for him. But the fact remains, that he deliberately used lies and deception to gain a high social position in a very politically derisive context. It couldn’t have come as a surprise, that every single racist out there would jump at the opportunity to pull him down should there ever be doubt about his academic work. Plus the people, who really care about academic integrity. Plus a whole lot of folks who simply do not like people blatantly lying for massive personal gains. The vitriol was entirely predictable. The internet is not known for being forgiving. He very deliberately and knowingly took a huge and, given the absurdity of some of his claims, unfounded risk the materialization of which he could not handle. I do feel sorry for him to have started on this path. What state of mind would push a person to take such risk? He must have been a tortured man long before it all exploded into the open.
