I guess everyone has different standards. I know little myself so I will take the opinion of the pilot I know the best and who has standards he sets for himself that are of the highest possible.
My brother, Brent, said one word when I talked to him about this very same occurrence, "Unforgivable".
No offense here but... Yeah, Brent has never had an oh sh-- moment. Give us a break, bruh. He knows better and I bet if you ask him he will share a few of those stories, because we ALL have them. Anyone who says otherwise is a damned liar.
There are those that have, those that will, and those who almost did/will. Experience is still the best teacher and lessons are often learned by coming awful close to making a boneheaded mistake.
I will say it again. Human factors can only be mitigated, never eliminated.
These things happen. We can learn from them and try not to copy these errors ourselves. Getting puffed up and tempting the gods with hubris is a surefire way to bust one's ass.
