I don't think that building wells in countries with corrupt governments is evil. I do agree with points in your older post about all of the able bodied people leaving for greener pastures in foreign countries being a problem, and just throwing infinite aid at them, i.e. a bunch of clothing that destroys their local markets. You need capital to build certain kinds of infrastructure and if their local governments are too corrupt or inept to do it themselves, then it isn't a bad thing for a third party to step in and help.
