I think there are many ways to make a character’s death really sad, and bc we can all have different feelings about a given character, any individual reader will be very sad about the death, when another reader might be totally indifferent (or even glad!). I’ve only written fanfic myself, and I know what makes me sad when I read/write character death, that’s about as informed as I am on the topic, DISCLAIMER: I’m not a professional writer and this is not professional advice.

💀 Some things that come to mind re: making a character’s death really sad: 💀

1. How they die, 
2. How preventable their death was, 
3. How other characters feel their loss and/or the loss of their potential, 
4. And how much that character meant to the reader/audience, did they like the character?

I don’t know what specifically you’re doing in the Memnoch timeline… I won’t use any examples of deaths from that book in case of spoilers (Idk sometimes I’m more respectful about spoiling ppl than other times *shrugs*)

In IWTV, it was a very sad death when Claudia died. It’s portrayed differently in the book(s) and the movie, but I’m just going to address it re: the points above generally and drawing from both.

1. She died by sunlight exposure and it seemed extremely painful. 

Louis would not have seen it, so he can’t describe the moment of her death in the book, but it’s shown in the movie. Leading up to the death, the tension builds and builds, all these moments where Louis, Claudia and Madeleine are hoping for Armand (or some other deux ex machina) to swoop in and save them all. It doesn’t happen. Probably one of the last shreds of hope they had was when the troupe pull Louis and Claudia apart, from that point on, he can no longer protect her ;A; 

As it was so painfully underscored in Claudia’s Story, the last name Claudia hears Louis call for is “Armand,” bc calling her name won’t do them any good. But to her, it feels like a final betrayal, that he’s calling for Armand bc he cares more about him ;A;

Claudia and Madeleine get locked in the well, and when Claudia sees the sunlight approaching, she’s already starting to cry, trying to wake Madeleine to try to figure out a way out… there is none and then they can only brace themselves bc there IS NO ESCAPE ;A;!! The acceptance of their own deaths is part of the tragedy.

It’s a pretty universally nightmarish situation, even though sunlight is not fatal for ppl (most, anyway), but we can all relate to the experience. It’s like being pushed onto subway tracks and not being able to escape in time ;A;

2. Her death was a failure in diplomacy, basically. The Theatre des Vampires, led by Santiago, held a kangaroo court (although they may have felt that they were within their rights) in which they found Claudia guilty of attempted murder of her maker, and decided to punish her with the death penalty. 

Louis tried to protect her from it as best he could, he tried to make a deal to save her life, but failed. In the book:

“ `Listen to me, Lestat,’ I began now. `You let her go, you free her… and I will… I’ll return to you,’ I said, the words sounding hollow, metallic.

3. It kills a part of Louis when Claudia dies. His immediate reaction is extremely sad (not even factoring in the revenge he takes after).

I have a more thorough commentary on this scene here. It’s in this moment that Louis has lost the most precious person, the one who’s told him what to do, someone he could worship and follow, someone who metered out his doses of happiness with her approval. In the movie, he calls her “my child,” Armand tries to correct him: “Your lover,” and Louis compromises with “My beloved.” 

In the book, the next night, Louis finds Lestat clutching Claudia’s bloody dress and sobbing over her death, too. Even though he was the very person who testified against her! Even he could not prevent their “justice.”

“And then I saw the thing in [Lestat’s] hands. I knew what it was. And in an instant I’d ripped it from him and was staring at it, at the fragile silken thing that it was – Claudia’s. His hand rose to his lips, his face turned away. And the soft, subdued sobs broke from him as he sat back while I stared at him, while I stared at the dress. My fingers moved slowly over the tears in it, the stains of blood; my hands closing, trembling as I crushed it against my chest.

Louis was expecting Claudia to go on and live with Madeleine, that he would still be in touch with her and see her occasionally. So that potential continued relationship was destroyed, too ;A; 

4. What did Claudia mean to the audience/reader… 

I know I sympathized with her and very much enjoyed her overall, and I like to think that other readers/viewers agreed, and don’t totally blame her for her actions against Lestat… after all, she was a victim herself. Lestat doesn’t blame her when he speaks of her in canon. We saw the love they both had for her ❤

Is that enough to convince the readers/audience to care enough for her that her death is sad for them? All those factors help!
