That's a good idea. An actually unique idea. I've felt bad having to kill companions in some RPGs where they were well characterized. However, usually killing them was a last resort, not my objective. It would be interesting to see how I would feel about killing people I like when that's my only mission, not just an unfortunate side effect.
The enemy AI would have to be off the charts though. That might be the one most difficult thing.
