You seem to have two different questions here. The first is about whether there are people who don't won't consider ethics when doing their research. I'm sure there are such people, but they still need funding and other support that they'll lose if they don't follow the ethics guidelines of their institution and/or laws of their country. The scientist who recently announced the birth of genetically modified babies is a particularly strong example of these consequences. Your second question is about different ethical standards across the globe. You don't need a journal that completely ignores ethics to support people a global community working under different ethical systems. You either need a journal that accepts submissions that passed local ethical review or a locally-run journal that abides by the ethics of its locality.
