I never leave any I have left out after finishing my mining stint, I stay with them until they they naturally expire. Closest thing to pets we have so the least anyone can do is wait with them. Better still would be instructing them to come back into the hold and not leave them to their fate in the uncaring, cold, darkness of space.
They always remind me of Huey, Dewy and Louie, the drones in Silent Running. Sob, I'm such a caring softy.
Now excuse me, I've gotta go and murder Scavengers in a settlement somewhere.
