Earlier quoted context omitted.
One of my (very experienced) alpine hiking instructors died after a long day summiting Rainer. His team made a rookie mistake, but it’s surprisingly easy to do when you’re exhausted and you feel as if you’re nearly done with the worst of it.
I was told, most of the climbing accidents happens in easy terrain. When also experienced people get careless. My experience matches that.
While climbing most deadly accidents (30+% of them [1]) happen because people rappel through the end of the rope (or ropes if using half/twin ropes). Stopper knots are a 10s precaution that is often overlooked.
However, it is true that on easier climbing routes it is easier to hurt yourself because you might hit a ledge on your way down. If that happens it's most likely the belayer's fault because he/she should keep "a tight leash" on the sections just above said ledges. If you let an unexperienced person belay you I assume you evaluated the risk and are ok with that.
