There was a number of quests throughout the game where I didn't like the outcome and reloaded an older save to try a different option so I could have tried it to see, though in this case I was satisfied with the option I went with.
The worst one for that was [Skellige quest spoiler->] the cursed werewolf in the garden. Even after doing all three options I couldn't decide which of the two outcomes I prefered. Awesome voice acting for the werewolf, I thought. Its suffering sounded really genuine.
