At this point
if Oda kills anybody
it would feel cheap asf
no impact at all
all those fakeout deaths have killed the mood completely
if somebody dies, we will spend weeks, maybe even months thinking "nah, they aren't dead"
then, when we come to the conclusion this character died, we would just say
"well, whatever then"
Oda is like Usopp in Syrup Village, the boy who cried wolf
