The mentioned climber and climber woman already missed the route entry. For half the route they spent more than 6 hours. They climbed with one small backpack, so almost without survival gear in the mountains. When they arrived at the ledge after the second gully, they could, given the spent time, decide for descent. The route is called Južni raz and goes along the raz so you can't miss much if you have some experience finding natural passages or at least the multitude of pegs sticking in the wall. You gain that experience if you climb several routes with experienced alpinists. A completed course, no matter how successful, doesn't give those experiences.
In my opinion they made so many mistakes that I can say it is negligence. If this trend continues, we will all get at least a bit "stuck" and before dark order transport at taxpayers' expense.
Of course I am glad that in the end everything ended happily.
Alpinism is not tourism.
