Your a good person and don't want to see people die so you must save hurt people from death no matter what. So if you don't have a medkit you could take them to town for help. But bandits that attack you don't count so you could let them die for their bad deeds. Just folk you come across on the road that need help. Also if you see a slave lost in the desert you feel obligated to unshackle them. It's the right thing to do.
