Is there anybody alive who loves violence? Wouldn't we all rather live in times of peace? Even soldiers - especially soldiers - mostly they tell the same story. If we can avoid fighting, let's avoid it. If we have to go to war, let's fight to re-establish the peace. War is a soft-skinned newborn, just days old, buried under cinder blocks and broken glass. Anybody who professes love or even tolerance for war, they never feel the same if it visits the block where they live.
The problem is that the people shooting and the people getting hit by bullets no longer have the power to just say stop. Often they aren't even sure what the fighting is about. They're just pieces of something larger, set in motion by men sitting in places of safety. In the neighborhoods and squares where people are dying, no amount of reasoning with the enemy, no amount of empathy, could stop the killing.
Even if you know all this, there's a point where it becomes something you can't escape. If you've been pushed down or beaten enough times, without understanding why, you begin to push back, to fight. You enter the spiral of violence like everyone before you. There's no choice.
