There's no amount of evidence that will convince the hardcore denialists. One of the organizers of Germany's biggest anti-mask protest actually ended up in the ICU 8 days after a rally, yes of course due to Covid, he even got intubated and everything, and now he's released from the hospital and nothing has changed about his views. I'm 100% sure that if he had died from Covid, his fans would have just made something up about him being assassinated by Merkel or whatever.
