@Dastern sadly we live in a world where payment processors can put a lot of pressure on companies to have them censor or not release content they deem problematic, so even with enough demand a series like Redo of the healer might be considered not worth the risk.
Personally I started reading the manga out of curiosity, I don't know how much different is from the anime or the LN but I didn't find it unbearable, partially due to my tolerance to objectionable content being much higher when it's done to horrible people. I'd read the LN if it ever gets licensed here, but I don't think it's going to happen.
