I get what you mean and it's a case by case basis, if people didn't try and push any morals we would all live in vacuums where all we have is the law to tell us what is _right_.

A lot of people have no problem with their countries governments manufacturing and/or selling arms to dictatorships that inflict harm on innocents and supply extremists e.g. UK-Saudi arms trading. As far as some are concerned the UK is just doing what another country may do instead.
