Personally if you were to ask me about his death, i'd blame the cancer for killing him, not the 'science' he investigated in an effort to fix the problem.
But I don't hate cancer, it's a natural thing, but I do hate homeopathy because it's 100% man made quackery.
If one of my relatives died sooner because they had been let to believe to use this nonsense I definite blame the salesman of scamming my relative of money, trust and a longer life.
It is the same as the Christian church in the middle ages selling salvation for money to dying people. Despicable.
It goes beyond simply wishing he hadn't died, too. He managed to finagle a healthy liver transplant in the process, which might have gone to someone with a better chance of surviving with it longer.
