The example of “ones” given in SS”K is a lady taking care of her sick son. That does not sound like a “complete ones” to me,
Why not? She did the right thing to take care of her sick child instead of lighting candles.
You did not do the right thing when you mismanaged your time and arrived too late to light, or overslept (unless you were literally too I’ll).
(I’m speaking from a halachic perspective, not trying to give mussar.)
