Well I don't want to be entirely a pacifist, so I might just ignore the achievement, but I am not the type of person that will kill everyone in a room if I can help it.
One thing of note that is kind of odd, but do you notice that taking the non-lethal approach is often way more rewarding? A non-lethal takedown is not only more silent, but also gives more XP towards Praxis Points. Seems like a no-brainer that you would do the non-lethal takedown. If you really want the person dead you can just shoot them in the head after they are knocked out.

One of my favorite moves is to open a door while a guy is looking at it, then hug the wall. They walk through the door to check out why it opened and you do a takedown on them as they pass. I liked it because it was a realistic way to get the jump on people.Although I never even installed any silencers... I want them to know I'm coming.
