What did Fisher do to try to get Lester's body? How did this affect Fisher? Should he have done this? Why or why not?

Fisher and fisherman George Burlew made repeated dives into the murky water but could not find Lester. Just before they gave up, Fisher decided to dive one more time. He resurfaced and told Lester's waiting parents and the others who had gathered that he found the boy. Just then, he was attacked and taken under by the shark. Fisher was an athletically built man and battled valiantly against the shark. He was finally able to get away from it and was carrying what was left of Lester to the shore when the shark attacked again. Fisher got away again but the shark took Lester back with him. Most of the flesh on Fisher's thigh from his hip to his knee was gone. When a doctor was finally rounded up, he observed that the bone was not severed but his femoral artery was bleeding profusely. Fisher was placed on a train to the nearest hospital, which was ten miles away. The doctor doubted that he would survive the trip. I have great respect for Fisher for risking his life to find Lester's body. If he felt he had to try, then this was worth the consequences.
