What do you mean by leaving? If you meant reaching the root, it's not exactly a portal that leads outside.

Okay, pardon, but I'll need to get some clarification here and there, if you don't mind.

so, what do you intend on using your gore for?

You want to use it as a technique through which you can criticise immortality? How so? I can't see how the experience of gore (and, therefore, the experience of seeing yourself get injured and all,) works to subvert and criticise the concept of immortality - surely an immortal would, by a certain point, have learnt to get over all the icky things that happen when they die and then promptly un-die? I mean, the general idea is that gore is feared because it's a reminder of mortality - the fact that we're all a bunch of squelching biological machines that could just shut down at any moment like any other machine. This is a fear that is irrelevant to an immortal, hence the name!

What is your point about video games? Is it that people try not getting killed because they want to avoid gore? I mean, I doubt it's that point - plenty of videogames lack gore and you don't want to die in them! Not-dying in videogames is more easily attributed to the whole 'I want to win and not lose' mindset. But, yes, I'm not sure what your point there is, pardon.

What do you intend to show by 'describing in graphic detail how it (presumably the gore) hurts the character physically and mentally'? Does this relate to your earlier mention of wanting to criticise immortality?

Also, surely the lack of death in Mount and Blade is more of a game mechanic, than a function of the game's canon and worldbuilding? Surely death exists within the plot, and world and all, the plot and world and all being the things relevant to fanfic, over the game mechanics, oy?

I disagree with the notion that tragedy requires gore, because that is a nonsense notion. It is a tragedy when a young boy grows up without a father figure because his dad's passed away from diabetes type-two, and it hardly stops being tragic by not having any gore about! Or did you mean something else with that point?

Your last sentence lost me completely. I'm not sure what gore has to do with a character atoning for crime in the eyes of their mates if they become a bandit.

Yes, ah, pardon for the barrage of questions. Clarification'd be helpful in getting your question, y'know?

I find that a lot of authors who like to use violence use it much too often. Which in turn, makes the entire thing look very artificial. Think of how the characters think, or how a gamer might percieve enemies in a game. One would not notice a mook or redshirt that got killed by the protagonist. In such cases, a simple phrase describing the death should suffice because no one, not even the one performing the killing, cares about it. On the other hand, if this was a final battle of ultimate destiny against a nemesis, or a boss fight, or anything of emotional significance, then the character begins to notice details.
Adding details of the act will add emotional significance to the killing, or hurting, of a character. Basically, it is the difference between "seeing" and "feeling" the violence. So, if the violence is not significant to the characters and plot i.e. hurting a mook, then intricate details should be used less. If it is significant, then more details could, and should, be added. If it is very emotionally significant, then you may do tiny details of you so choose. Although this is my own personal views.

And yes, gore can be used to point out weaknesses of immortality. In fact, this was done in baccano.
