Thats was my point. Cauterization curing (preventing) infection is like bloodletting curing flue. Granted, cauterization persisted a bit longer in real world. I get the point about wound being dangerous. I use a house rule of not using cauterization and antibiotics and disinfectant are at prime.
But perhaps there could be some sort of other treatment instead. There are some natural antibiotics from fungi, so perhaps with high enough survival/first aid skill… then again, perhaps crafting already covers that, i havent got it that high ever. And it would do nothing to starting characters, which have it hard enough, whereas its the old characters that have it easy.
