I might get some hate because of this, but whatever.
The Master Chief needs to die soon, in my opinion. He's survived some rediculous stuff, yes, and perhaps he's the best Spartan. Whatever. 343 Industries, as much as I hate them, need to move on. Halos 1-3 were good with John-117, and perhaps if Bungie was still making Halo, I would like the Chief to live.
But as it is, I think 343 is just going to further screw it up. I would rather them just have him die in Halo 6 than continue on, making crappy story lines that make him look like a fool.
There, I said it. This is all my opinion, take it with a grain of salt.
