It is not so much a question of being an "empty husk", as it is of just how much time Izetta has before dying.
I will copy-paste my opinion from another place:
In the show it is clearly and unambiguously stated that using the crystal shortens the lifespan of the user. It is why Fine is so opposed to Izetta using it. The more you use it, and the more power you release through it, the worse the effect is. Both Sophie and Izetta are aware of this, the former is just so hell-bent on revenge she does not give a fuck, while the latter would do anything to protect Fine.
"To win the battle, she stole a stone of power that the first witch had: the Magic Stone. It devours the life of a witch to overturn the laws of power." (Izetta's grandmother, in a memory, talking about the first Sophie, in episode 10.)
"The White Witch, the real Sophie, once said that the Magic Stone draws out the power of the witch by shortening their life. If you use it too much, you won't have long to live." (Said by Müller to Izetta, based on the diary written by his ancestors who were members of the court in Sophie's time, and were involved in the plot against her, episode 11.)
"If she crystallises all that magic at once, she'll die for sure." (Sophie's internal monologue, episode 12. This also indicates it is not just the duration of the usage, but the intensity as well, that drains the life from the user.)
Sophie unambiguously thought Izetta's move in the finale was suicidal, and given what we know about the Stone, this is indeed correct. Nevertheless, she tried to match it, given all the factors (nature of the Stone, the suicidal levels of energy being used, her previous usage of the Stone, and her cloned body), she ended up dying in the process. Izetta survived, but...
The scene after the credits is set several years (and it could not have been more, given how young Lotte is there) after the last duel, it only tells us that Izetta is still alive, and the main couple is still together, but how much time they have is anyone's guess (personally, given everything, I would say they do not have that long).
Now, I understand why people do not like this, but still, the only way you can give Izetta and Fine a happily-ever-after for a long, long time is if you deliberately disregard canon information. There is just no way around this. And the thing is, Fine knows this, as exemplified by the scene after the broomride, when they were on that mountaintop (episode 12):
F: "What? But that magic stone eats away at your life, right? If you do that..."
I: "It'll be fine."
F: "You're lying. I can tell right away when you're lying! Especially when you're lying because you're about to do something crazy for me."
I:"I'm sorry. It's true that I might die. But there's something I want enough to do it anyway. A world where everyone can choose their tomorrow. A world where you can smile. ... So give me the order to fight as your witch, Archduchess, no, Fine... And to end it all."
F: "No!"
I: "I've given it a lot of thought, but I couldn't think of anything else. So..."
F: "Izetta... Izetta... My witch... I order you... you..."
And the scene cuts to Fine breaking down and yelling at the representatives of the warring powers, from her grief it is obvious she is fully aware of the consequences Izetta's actions will have.
