Honestly, I was expecting the MC to comfort the guy by telling him that they just need to survive this stage, and the rest of the tutorial will be much easier in turn.
That is the reason the MC chose the red door to begin with.

Yeah, no reason for her to outright die, and I'd be surprised if she'd have no redemption by the end of that stage. Writers usually don't create a small group like that, just to further decrease it.
A group of 3 people is pretty much peachy for the start of the story.
