The idea that failures can and should still lead to progress in other interesting and ultimately positive ways is a concept that Larian have paid some lip-service to, but not actually shown any signs of delivering on so far - just the opposite in fact, unfortunately.
I mean how funny might it be if we tried to clear the jump and failed, like with dragging finger nails and then a drop "Nooooo!" but somehow we slid down to the lower level and bypassed all those Imps to meet Gale or Astarion first, instead of Lae'zel and Shadowheart. That might work hehe.
This is an excellent example of the sorts of ways that important checks and saves failing can be made interesting.
