Right, it makes absolutely no sense with the actual lore of the game. If you read the books, Chief realizes and accepts at a young age that he won't see his parents again and that he's now got a new "family" and is being trained to be a super soldier. He got augmented at 13 or 14. By 16 he was already fighting the covenant. They tried to make it a drama TV series (it's literally listed as that) so it was built to fail. The show would've been way better if it started with Chief as a child and showed the relationship between Keyes and Halsey, showing the other Spartans whom Chief was close with as a child and himself being trained on reach. Also would be cool if they showed what was going on on the covenant planets before and during the beginning of the human-covenant war, (giving us background lore to the arbiter specifically) while also showing us flashbacks of the forerunners to make sense of who they were and why they made the halo rings, what other attempts they made to wipe out The Flood, and why did they ultimately make the choice to activate the halo rings and wipe themselves out.

He eventually garners reasons to go against command, but that's after gaining perspective during his multiple, personal, galactic-conflict-scale triumphs. He doesn't have that perspective at the point in the timeline the show is meant to take place.
