Shane does make a good moral and ethical case, though we are more often tempted to side with the more empathetic Rick. The good of the many does often trump the good of the few, or the one.
I don't make that comparison. Had it been something like a grenade thrown on a boat of many and then thrown to a boat of one (assuming no other options were available) then I'd see that as more viable.
