Ahsoka TV Series (Spoiler Discussion)

Therein lies the problem though... There is too much of this going on in the new Star Wars stuff where the fans have to fill in the gaps and make up theories to explain inconsistencies...

Hard agree.

It's not so much that you couldn't survive a hole through the gut -- that happens with gunshot wounds all the time, and they aren't automatically cauterized -- as that if the person wants to kill you and you do that dramatic moment of the person impaled and shocked and motionless, all the attacker has to do is pull the lightsaber out through your side rather than the way it went in.. Maybe a parting shot chops off the top half of your skull.

Sure, you can survive a stab, but the fact that you're standing or lying there so easy to finish off and the attacker doesn't finish you off invites the viewers to ask WHY the character isn't dealing a coup-de-grace. Does the apprentice not actually want to kill Sabine? Surely the apprentice knows that people can survive a cauterized hole through the gut if we know that. So her choice not to finish off Sabine is intentional. It's not just her thinking Sabine was already dead.

What does that say about her? Is she merciful? Is she not actually loyal to her master? What?

We don't know, and likely we will never know, because it's likely (not certain, but likely) that the writers aren't even thinking about how silly it is not to deal a killing blow when you have someone helpless and you know that medical aid can save them.

And that just makes them bad writers who aren't thinking through the realities of the worlds they have created. It doesn't even occur to them that they need to stay consistent with the premises of lightsaber combat as established in 500 previous sources.
