I don't have the patience to read all of these... but here is my two cents.

Chara chose to die. They committed suicide. So their determination wouldn't have kicked in to save them because they CHOSE to die. That's if they even could save. Their life wasn't full of danger, so there wouldn't really be a need to. But the reason they actually died for real is because they were determined to die for their plan.

As for why Asriel didn't do the same thing... they likely didn't know about it. They didn't save, and monsters aren't used to determination in any case. It's possible that no matter how powerful a monster gets, they simply cannot save and reset because their bodies are simply not made to use determination. Even Undyne melts after trying to use determination in a neutral run, and likely wouldn't survive for long after becoming Undyne the Undying, logically speaking. If the determination can't save them in a neutral run, it's likely that her body cannot take that level of determination from being Undyne the Undying forever. She was likely dead as soon as she transformed, basically. Flowey is neither a human nor a monster, so it's not impossible to assume that they are not restricted by the rule of monsters not being able to save and reset. They didn't necessarily save, but when they died, they returned to where they 'started' as a flower, in Asgore's garden... or maybe Alphys' True Lab. Either way. They likely learned about the save points in the same way Frisk did. They saw the glowing, shiny spot, and examined it, finding out that they could use it to 'save'. And then all it would take is one 'accident' and reset to realize what it was.
