A knife stabs your heart, you're dead bruh. Feel free to show me someone else in this series who survived a stab straight through the heart. We literally see the knife go through her heart, there's no debate there. She also never got said heart back, let me add. If your only defense is that she hasn't been shown to be confirmed dead, then I can play the same card that she hasn't been shown to be confirmed alive either.

As for your "2 people" theory:

Roger was executed in front of several witnesses. Dead. Carmel's devil fruit has passed on. Whether you submit to the theory that she was actually eaten or not (because it wasn't "shown" LMFAO), she gone. Corazon was shot, and used his dying breaths to keep his DF ability active over Law while he escaped. Considering Law could eventually be heard speaking again....ya know......Plenty more characters not even on this list that should be....Toki, Jaguar D. Saul, and Nico Olvia just to name a few. Plenty of people in this series have died, or "died" since you want to be technical. You need to let this notion that Oda doesn't kill people off go man.....
