Compared to the ultra-violence that people are complaining about, yes.
I'm ex-military, among other things, and I don't have an issue with the murder/raider themes. These follow the rules of storytelling.
But when we're talking about dragging an NPC/player under a car with points for distance, or shooting a recently "loved" prostitute in the head to avoid payment, then I think we're talking about excessive violence and poor thought.
More John Wayne, less Natural Born Killers.
Mainly, I would like to see TDM more popular. It's a great game. There's wonderful stories, nice graphics, and it's thought provoking. Teens to adults looking for something different would love this, if they knew. Plus, with DarkRadiant, it's a great way to teach game creation (a real job), architecture, physical security (yes, I know that's sorta reaching), geometry and trig... a lot of things.
