In my current adventure, my PCs have discovered that the mystery cargo they've been contracted to haul is a group of slaves. The slavers have instructed the droid enforcers surrounding the group of slaves to start killing the slaves if the PCs don't comply with their demands. I was thinking this would give the Force-sensitives in our group some pause, but they've decided to rush the slavers instead and try to kill them all before they have a chance to kill the slaves. I won't say their plan can't succeed, but there is a high chance that at least one slave will get injured or killed.
This leads to a problem--how much conflict should the Force-sensitives get for this kind of collateral damage? I'm not really sure if I should give out conflict on a per-slave basis, say 3 points of conflict if a slave is injured, 4 points for a death, or if I should give them a significant amount of conflict, say 7-8 points, and go from there.
Any thoughts from other gamemasters about the best way to handle this? Thanks.
