The other day I saw a post about how it's odd that the arbiter (thel) would listen to the gravemind, when it's (in a very Christian sense) the devil, from the Bible. And if it was Christianity he would be considered a bad Christian for believing the gravemind.
I think the problem with this line of thinking is relating the religion that the covenant practices to Christianity, is very flawed. The gravemind isn't basically the devil, from the Bible, because the gravemind isn't just one thing. You can have multiple graveminds, as seen in halo 3, and the flood can exist without one.
And while I'm not very deep into the books (I'm just starting ghost of onix after a few months since I finished the flood) I am pretty sure that the covenant doesn't say that the flood is the end all and be all of evil. I mean they call all Spartans demons, but they don't refer to the flood or gravemind as demons as well.
Moving on from the flood itself, thel literally just got betrayed and thrown into a pit to die. Like Tartarus literally told him that the prophets told him to kill thel. The next we play as thel the covenant is already trying to kill all the sangheili. While, yes, getting told that halo is a weapon by both the demon that made thel, the arbiter and "the devil from the Bible" would probably not shake someone's conviction if they were so dead set on it. (Just look at Tartarus) But like come on PLEASE. The message is to not just believe things blindly. Thel is smart, and has already been betrayed by his beliefs and the prophets that have led him astray.
It's mostly a Christian belief that you should never question the religion or the church. And while I do think that the covenant acts much the same as the church, the sangheili aren't stupid. They are very respectable in battle and as tactions. You are telling me, that after being betrayed, and thrown down a pit, to talk with demons and walk out of there alive to find that the people you trusted are now killing your men, you would still side with them?
Not to mention thel's whole fight with the rebel leader. He has been confronted with that the covenant are lying to all of them, and he still follows his mission to kill the rebel leader.
This whole rant has been mostly wishy washy, but listen to me. The point of halo 2 is to think critically about things. A lot of the books follow the same line of thought. You have to think critically about what missions you are ordered for, or the religion you believe in. Just blindly following orders is bad. The point of the game is to make you think critically and how much it takes for you to get to that point. It wasn't like thel had one conversation with the gravemind and went "hmmm, I think it has a point" NO! THERE WAS SO MANY THINGS THAT BUILT UP TO HIM DEFECTING!
That is to say, we should think critically about things now too. Don't always believe what you hear unless you can prove it. You have to think for yourself. Make sure you understand the choices your making, or how blindly following others too. That is still a choice
