I believe they use Reapers because the Reapers terrify the Grounders to the point where they won't go near the tunnels. It guarantees 100% that the Grounders won't attack Mount Weather and try to wipe out the Mountain Men. They also might use the Reapers so the Mountain Men don't have to risk their lives (exposure to radiation or Grounder attack) trying to guard the tunnels themselves.

I don't think there's anything worse going on at Mount Weather than the Harvest Chamber and Cerberus Program. If there is, I can't imagine how much more disturbing it can possibly be. I mean, the Grounder being drained of their blood and Cerberus Program seem disturbing enough.
