The more egregious thing to me though is ignoring the GPWS callouts on approach because they were chasing the glideslope. If you can't maintain a stable approach, you need to go around, it's the first thing you learn.
You expect this behaviour from a first-timer in the sim, not a commercial cargo pilot.
I'm curious - are commercial pilots reprimanded for doing a go-round after messing up the approach?
However I will say that the majority of unstable approaches (97%!!) do continue to landing: https://flightsafety.org/wp-content/uploads/2017/03/Go-aroun...
...but I think that most of these unstable approaches are likely marginally unstable and only in one dimension. This landing was so far outside the realm of normal it's actually mind boggling that it actually happened. Pilots are trained to immediately go around without questioning it if many of the things that happened on this flight occur (such as not being in landing configuration well before touching down!)
