Also think about it, a one man one hostage situation against an army would not work well at all. The covenant would most likely be able to save regret, even if they didn't they would kill regret if they could kill the "Demon". Also the original plan was when there were like 33 spartans, MC was alone he didn't have his team.

We work as a team, we fight like warriors, and we will die brothers.
