Halo - Combat Evolved, who's fault?

[House]

I had this game on my shelf for like 10 years, and I was like meg let's play some with it, the original is the best
As I was going throught in the game, I was thinking like, when it's get to the level where you first meet the Flood, before that, when they try to open the door Pvt. Jankens say that "The Covenant did a pretty good job sealing up this door".
So who's fault was the Flood?
Is it our fault or the Covenant's fault?
So if Cap Keyes never would of openned that door then there wasn't gonna be Flood to begin with?
Why didn't they alert them, that DON'T OPEN THAT DOOR! FLOOD ALERT!

The flood being unleashed was the Covenant's fault. The whole Reason Captain Keyes said open the door was because he thought the Covenant were trying to hide something in there so he wanted to take whatever it was. When they entered it was too late. The Flood are parasites that can take over the host and then they become able to use any intelect the host had. Which is why the flood are able to use guns.

So it's the Covenant's fault.
