That is very true, but any decent FTO/RF has a duty of care to it's memers, especially when they are inexperienced/out of currency or both as this poor chap was.
I have often had to step in when I've seen more experienced PPL's jokingly bullying a less experienced member who's unsure about the weather.
"Och, it's not as bad as you think" or "What are you worrying about, I've just been up." etc.etc.
I don't think these things are acceptable as it then becomes a challenge to go up in conditions someone is unhappy with. Note I'm not talking about shocking weather like the conditions in this accident, but anything someone isn't happy with, be it wind, changing weather, viz, cloudbase whatever.
It doesn't take much to push someone inexperienced into doing something they aren't happy with. Clubs and schools should try and ensure that this happens as little as possible and support less experienced and less confident pilots.
