What are Ender's conflicts in Ender's Game?

I think it is pretty clear from the very beginning of the
story that Ender, through the course of this excellent scientific fiction novel,
experiences any number of conflicts that seriously threaten him. First of all, a great
place to start is considering how the series of external conflicts that he faces are all
stage-managed to a certain extent, or observed. Note what the observers who watch him
say at the beginning of the second chapter, after Ender has just beaten up the gang
leader effectively:

"I went back through some of the tapes. I can't
help it. i like the kid. I think we're going to screw him
up."

"Of course we are. It's our job. We're the wicked
witch. We promise gingerbread, but we eat the little bastards
alive."

We cannot escape the
disturbing conclusion that Ender is being formed by the violence that these observers
either deliberately unleash upon him or sit passively by and watch him suffer. It is
only through these experiences that Ender can gain the necessary skills and qualities
necessary to save mankind, it is suggested.

Of course,
Ender arguably experiences internal conflict as well, coming from the immense pressure
he faces when he begins his "education" and starts playing the "Game." Ender's whole
life is one massive exercise in conflict, which results in an individual who has been,
in the words of the observers, "screwed up" or "eaten alive."
