He seems to have lived his life on his own terms. That alone deserves respect.
Too bad he gave up on reality and started drinking the Kool-Aid. Happens to a lot of successful people, they think that just because they are successful at one thing they are experts in everything.
The reality is that many people successful or not don't like being told what to do regardless of the consequence. I don't think there is any new Kool-Aid involved wrt the mask. Sure, the science is out; the science is out on many things which we also ignore on a daily basis without any consideration. Speeding, smoking, drinking alcohol, using drugs, unprotected sex, going to the Moon/Mars and not wearing your seat belt... Some people are more inclined to take risks than others.
I'm not going to condemn the man based on that one thing - it was his choice. Maybe his death will serve as the motivation for others who are on the fence about wearing a mask to put one on; especially those who are in the "more susceptible" categories.
