Sorry, aarco. On the one hand, I agree...perform the role you have taken on.
On the other hand, if you have the training and the skills to do more, IMO, you'd be the biggest asshole on the planet if you could have used them to save that guy from getting hurt...and didn't.
If it's a "Coach" jump, then your agreement is to turn and track, and even dump - at the agreed hard deck - so the student sees that. Honestly, I think that's the best way to save that guy from getting hurt. (I could come up with exceptions to that rule, but that's my baseline)
Dive the plan. If the Coach (even AFF rated) deviates from that plan (i.e., let the dive get low enough that they feel they need to 'save' the student rather than show a turn and dump at the planned altitude) - then the Coach screwed up.
The asshole is usually the guy that changed the plan.
