For this reason, I sometimes wonder if guns make it easier (psychologically) to kill another person than with something like an axe or a club. Sure, it's a soldier's job to engage with an enemy, but if people understood the sheer brutality of willfully ending the lives of other people at its most basic and visceral level, then I really wonder if people would be so at ease with allowing military action to take place.
I also think that if people had more direct exposure to slaughtering animals for food, or even had to do it themselves sometimes, they might have a greater understanding of the value of human life, not to mention what good meat should look, smell, taste and feel like. None of this factory farmed, corn-fed shit. Of course, even slaughtering something small, like a chicken, is kind of a pain in the ass.
