A culture where there is no danger? I suppose that is what many call a Utopia. However, the only way to reach such a culture would be to remove all evil. The problem with that, is that evil isn't a thing. That is, it is a lack of a thing - good. Therefore, evil cannot be removed unless everyone becomes righteous. Obviously that is impossible for humans to achieve, as humans are imperfect. Therefore, a culture of safety cannot be achieved by humans alone.
