It depends on what the person did. Lovecraft was a racist, but never hurt anyone unlike this guy, so I think it is fine to buy his books.

I honestly think that Lovecraft might have suffered from some mental illness, the guy had so many phobias. His childhood wasn’t good either, he was racist because he genuinely thought they will kill him or hurt him.

Also he doesn’t get paid if you pirate them. So feel free to pirate them.

H. P. Lovecraft was very racist and you can even see his racism in his books, and people still read his books. You need to disconnect the author with the books, although Lovecraft was racist and not a monster like this guy. I even heard he tried to change before he died.

I wonder if studies are performed before decisions like these are made. Just look at what happened in the four pests campaign in China, before doing any killing studies have to be conducted to see the affect on the ecosystem.
