This is One Piece bro, you have to get used it.
Nope
Many readers already have the expectation that nobody dies so when somebody does they expect the character to return 1 or 2 arcs later. Pedro being an example, we had people DURING WANO expecting for Pedro to return with the lifespan of the homie.
There are people who think Kidd is alive. Nobody expected half of the scabbards to die, nor Yasuie being killed on panel.
It's time we get used to the fact that indeed, Oda does kill characters these days.
Besides, Harald staying dead and Ida potentially being alive would be a nice reversal of the usual dead mom and deadbeat dad tropes.
