Review Detail of Kainedei in Halo Reborn

First, the first chapter is just a log, it's not even a chapter. Second, the MC has everything given away and that's not bad, the problem is that he gets everything from the beginning and without any effort. Third, why is God/author going to improve the intelligence of MC, who is one of the most intelligent humans in history? He could give him some other ability that would be useful or improve his strength or speed a little, but instead of that improves the intelligence of one of the most intelligent humans, really? and for what?, so that he then behaves like a conceited idiot who knows everything and shows his abilities, that is, his inhuman intelligence to the ONI, yes of course, as if the ONI did not mutilate people, murder children or exterminate planets just because they think different from them.
