I wasn't really going for shock value at all and I think it's an important step in her character arc. If anything it's tame compared to the two story quests after it.
If I wanted to have shock value I would hit Kit with a car lmao. Without what happens in Experiments, the character in question wouldn't have the chance to grow and learn to accept and forgive what happened to her and then you wouldn't get to see why she's a good person through how she takes it.
Basically, it was important.
