There's an achievement in MGS4 for completing the game without killing anyone, alerting anyone, using recovery items, dying, using stealth items, and under 5 hours.
Why would it surprise you that the next game gives you a similar option? It's probably an achievement.
Also, you may not have to kill anyone in Half Life 2. It would be rather difficult though.
