Hey James. I can totally respect your view. I think the difference between you and the people who go into the military goes to a very deep philosophical position of the nature of good and evil.
People in the military tend to believe evil exists and there are those in the world who would do harm to the weak. That is the assumption they are operating under. It isn’t that they enjoy violence. It’s just a necessity of existence.
But yours is a noble cause to aspire to too. Perhaps these two ideologies can coexist in some ways.
