I think another term would better fit your description. Maybe “executive failure”.
It seems to me that there’s a bunch of terms/concepts which all seem like they fit/are relevant to some extent here, including (off the top of my head):
executive failure (I’ve never heard this, and don’t think there’s a need to introduce the term if it doesn’t exist yet, but I can see why it’d work)
failure of willpower
failure to follow through
How relevant this is depends on the specifics
Which term is most appropriate in a given case will probably depend on the specifics and on the author/speaker’s aims. And it would probably be good for people to more often think a little more carefully about which term they use, and to more often briefly explain what they mean by the term.
