Even in its final moments, the whale didn't struggle against the people that it had thought it was friends with.
However, it did see that it was the humans that were controlling the boats that had attacked it, which completely shattered its heart.
In its final moments, the whale turned to look at the little girl with a betrayed look in its eyes as they dimmed.
The little girl saw this and her heart broke, as her world collapsed around her. Everything that she thought that she could believe in was suddenly gone and all she was left with were people that seemed like wild animals as they butchered the corpse of the whale.
They cut the whale up into smaller and easier to carry pieces which they brought back to the village.
