The Breaking Bad wiki also has something similiar, with their own "List of Deaths". I'm not a good editor, just want a suggestion. Here are some of the major ones throughout the series:
Phantom Blood George Joestar - "JoJo, it's not so bad... to die in the arms of your own son." Bruford - "Jonathan, I grant you the word engraved into the sword given to me by my queen: Luck! And for your future, I grant you this: Pluck!" Zeppeli - "You feel like both a son and a best friend to me, and now I will live on ... within you." Tarkus - "Enough talk, you little brat!" Dire - "Thorns from a rose infused with hamon are quite poisonous, aren't they?" Jonathan - "Fare...well... Erina..."
Battle Tendency Esidisi - "That's it! You've pushed me too far! Dorarara!" Possessing Suzie Q: "And now I will explode this girl's body, and cover you all with blood as hot as lava!" Caesar - "JoJo, this is the last of my Hamon! Take it!" Wamuu - "I am glad I was able to witness your growth. Perhaps I lived these thousands of years in order to meet you at the end. Fare...well... Jo...Jo..."
Stardust Crusaders Abdul - "Polnareff, Iggy! Look out!" Iggy - sad dog noises Kakyoin - "It's a... message. It's the best I can do... Mr. Joestar... Please understand. Please, figure it out..." DIO - "What?! I-Impossible... I-I'm Dio... I am Dio!"
Diamond is Unbreakable Keicho - "Don't touch me! You'll be dragged in, too! D-Damn it! It's taking the bow and arrow! Okuyasu... you were always holding me back!" Shigechi - "Joooooosukeeee!!" Dr. Aya - "His face..." Atom Heart Father - "Yoshikage!!" Kira - "I'm gonna push it... I-I'm gonna push it... I'm gonna push the switch right now..." As a spirit: "Wh-Where are they going to take me?!" Reimi - "Thank you, everyone. Goodbye, everyone." (spirit only)
Vento Aureo Abbacchio - "Oh, fine. Step aside." As a spirit: "Y... You're-! That's right! You! You died on patrol because I took that bribe!" Polnareff - "He who fully controls the arrow... will control the world!" (Before soul moves to Coco Jumbo) Narancia - "Got him!" Doppio - "Yes... If you're in there, Boss... Victory is guaranteed for us! Haha... ha... But... I miss you ... boss... Call me... Like you always do... I'll be waiting... Call... me..." Bucciarati - "Just try and read my future movements, Boss. Try to figure out what I'm going to do in a few seconds. Try to see beyond time. You should be able to see me after I've reached the first floor." As a spirit: "Giorno... This is fine... Don't worry, Giorno... The fact that we made it here... Is a complete victory... This is good... Everything will be fine... Fate is a sleeping slave... We have set it free... That is victory..."
Stone Ocean Foo Fighters - "No... it can't...! No...!" As a spirit: "But that will probably be another Foo Fighters. It probably won't be 'me'... 'this' is me. This is me saying goodbye. I'm glad I was able to say my goodbyes to you, Jolyne... It's all right, Jolyne... It's all right. I'm glad you got your disc back..." Weather Report - "This is the end, Enrico Pucci!!!" Hermes - "Wh...Where is he planning to attack from?!" Annasui - "Get ready! Mr Jotaro, Not yet! Not yet! Now! Stop time—" Jotaro - "ARGHHHH!!! Knives!! While he was falling...! The priest has already thrown them! Just like Dio had once done...! ORA ORA ORA ORA ORA!!!!" Jolyne - "Come on, Father Pucci! Stone Free!!" Pucci - "Stop!!!! You don't understand anything!!"
Steel Ball Run Mountain Tim - "I never expected to die on a bed. I'm a cowboy. All I wanted was a place to come home to. Just a place to return to after my journeys..." Ringo - "Welcome... to the true man's world... " Sandman - "I feel no morsel of regret... Not even equivalent to the smallest grain of sand in the desert... not an inch. The only worry I have... is for my sister. Who I have left in my homeland. I want her to be happy... my only prayer... is for her." Wekapipo - "Truth?" Diego - "The bastard... was definitely... cut to pieces... Valentine died instantly. I've won...! The one who was victorious was... me!" Hot Pants - "Whaaat?! My spray isn't working! Th... The window frame has gone inside my body! And it's moving! Th... The spider and... the other bugs in my arm! Oh no! Oh no! I need to get them out fast! ...N-No way. Something..." Gyro - "I always tried to take the fastest shortcut in this Steel Ball Run race, but the shortest route was a detour. It was the detour that was our shortest path. It's been true the whole time we've been crossing this continent. And because of you, we were able to take that route." As a spirit: "Hey, Johnny... Johnny... over here. Over here. I'm moving... over this way... If that's how it is... I'm okay with it... My real name... you promised, right...? Don't tell anybody. See ya... take care." Valentine - "My heart and actions are utterly unclouded...! They are all those of justice." Alternate Universe Diego - "Doing something like this to me... The victor is I, Dio! ...Stop! I'm at the pinnacle of the world... Stop this! You're just a shallow scum of a little girl! How dare you do something like this to me! I won't let you live! Wry! Stooooooop! Wryyyyyyyyyyyy!"
