The US and UK nuclear programs - commercial and military - are littered with incidents, many of them fatal or releasing significant quantities of radioactive waste. In one case, someone was likely murdered as part of a coverup (google Karen Silkwood.) The attitude during much of the US nuclear program was "you're either with us or you're for those commie bastards."

In Japan, TEPCO demonstrated a long-running, stunning disregard for safety that led to the Fukashima disaster (and it was not Japan's first nuclear power plant disaster, either): https://en.wikipedia.org/wiki/Fukushima_nuclear_disaster#Pri...

And as a reminder, Chernobyl happened because a bunch of engineers were basically engaged in a dick-measuring contest, likely to satisfy some apparatchik.

I'd say the world's nuclear power programs have demonstrated extensively that humans as a whole can't handle the responsibilities, and now we have numerous, much safer alternatives.

It's an absolute miracle we haven't had an accidental detonation of a nuclear weapon near a population center given bombs have even been released from planes, in some cases with multiple safety systems satisfied - and that the permissive action link system was almost completely bypassed by petulant air force commanders who had weapons set to (I wish I were making this up) codes of all zeros.
