Not that many people died in these incidents - because those zones were evacuated at great cost.
And to try and project the risk from accidents that happened so far is just foolish. The risk is really not computable because the chance is small (fat tail) and the consequences catastrophic. Additionally proponents want/need to scale up nuclear power (and thus the risk) by orders of magnitude to make a dent in carbon emissions.
And then, on top of all that, any small amount of actually bad intentions or simple incompetence throws off all the careful risk calculations.
The risk of a disaster is a different matter I don't want to get in to, I think people just fear what they don't understand. By this point, the people making and running the things know what they are doing in my opinion.
