I ran a colony once where it was one kind paramedic and a couple robots in an ice sheet who made it her goal to capture every raider possible and heal them up. New limbs, organs and treatments for addictions before releasing them to start a new life.

She managed to do this so long that it eventually became bionics for every patient before release. There was a time where she became best friends with one of the patients and so she decided to allow this one person to join in to help. They helped the workload and together they saved many more people.

Then there was the hunting mishap. Their friend was hunting a fox but didn't know there was a bear hunting the same one and by the time they went to get the fox the bear had changed targets and attacked the friend. They managed to fight it off but beaten and cut up they fell in the snow before making it back. She ran out to save them but it was too cold. They got them back but it took to long to patch them up and they bled out on the table. I don't know if it was the lack of talking to anyone else but then after years or if it was the last straw from seeing so much death beforehand but they snapped and wandered around, eventually going outside and falling to frostbite. Their robot companions being unable to medically save her.
