Every time, Ender makes a friend, he gets cut off by the military leaders, who think that his intensive training precludes his need for such triviality. He must learn to depend on no one but himself to get out of every situation, Graeff reasons.
So when he is surrounded by bullies who could seriously injure himself, the teachers don’t rescue him. He’s left to his own wits.
The teachers praise him in front of the other trainees knowing this will create envy and jealousy.
When he makes a friend in a platoon, they switch him.
There are many elements of madness in Ender’s Game that seem to lift from Catch 22.
The kicker is that this heartless abuse works. At the end, Ender saves Earth from the attack of the buggers with his brilliant command of the international fleet.
They talked of stoning David. Amalekites had attacked his camp while he and his men were out. They had burned it, pillaged it and made off with everybody’s wife and children. David’s men were embittered.
Then David did something extraordinary. The Bible says he encouraged himself in the Lord. No one was there for him. He dug deep and found the resource to turn the defeat into a victory. He pursued the attackers and recovered everything and everyone unharmed.
Maybe God let’s his servants go through times of utter loneliness to bring out the best in them.
