I'm having difficulty deciding whether you mean what you write or simply hope to provoke reactions.
I realise that, like me, you're a PPL but can you really not see the catastrophic consequences (for him and/or those in the helicopter) which might easily have resulted from this man's idiotic behaviour?
It's all very well to say the pilot should have dealt with the threat to the helicopter in a different way.
Perhaps you would have reacted differently.
And perhaps the outcome would also have been very different.
What we do know is that what this pilot did worked.
