I enjoy a good retelling of fairy tales and legends. I'm not really a purist in the sense that I like an occasional updated version that changes the story to make it more applicable (The Odyssey), or one that experiments with characters to how else the story could have been (Maleficent).
[THERE WILL BE SOME SPOILERS AHEAD]
In The Death of Robin Hood, we get a villainous Robin, one whom the tales and beer hall songs have rehabilitated. Close to the beginning, he offers this description of himself.
"I have known those who met this man. Would you like to know a secret? He never prayed once in his life. These tales spread across the land are lies upon lies. He were a murderous brigand, who perhaps cut the throat of a sheriff in a long line of others. People saw a meaning where there was none. He was not a hero. He robbed and killed for the joy of it, nothing more… I would say if you met this villain Robin Hood, you should make haste away and keep whatever life you have left here."
Soon after - and for first part of the movie - we see that play out. He's brutal - savage, even; emotionless; uncaring of the terrible harm he causes to innocent people. It's really unsettling to watch, which I think is the point. Robin Hood is not a good person and neither are his friends.
When he wakes up at an island priory in the care of a prioress (Brigid) after nearly dying from battle wounds, we move into the most important territory of the movie. Is there hope for someone like him? Can he feel remorse? Can he be forgiven? Can he start to bring goodness into a world that he has filled with evil?
There are signs of hope. A young girl latches on to him as a father figure, and it seems to soften his heart such that he actually starts to care about people. When he realizes a young man has snuck onto the island to enact a revenge killing, he rows the boy off the island and onto the mainland, where, rather than killing him, he gives a speech that suggests regret.
"How many men have you killed, Godwyn? How many children have you killed? I have killed so many, I could not give you a count. For longer than you’ve been alive, I’ve been killing the kin of those I killed a lifetime ago. I do not remember the first, who meant nothing to me at the time, but… their brothers and their children, their grandchildren, they remember me. So now I must kill them. Again and again. In different forms, like shades. Again and again, and it never ceases. It’s a curse, Godwyn. And it’s one you bring on yourself, even if done through duty. It cares not about your duty. This world cares only about blood. And blood is all it will give in return."
The death of Robin Hood is at his request. I am not sure if he finally realized how much he deserved to die after hearing Brigid's story, or if he was just tired, which he noted at the beginning of the movie. In the end, he asks her to take his life (though bloodletting). This is a really uncomfortable ask, as Brigid is a healer.
Brigid: “I have never taken a life before.”
Robin: “Ah. It can be as if pruning a flower.”
Bridgid: “Well, it should not be.”
Robin: “Aye, it should not.”
