During the two years of his illness, Charles chose the type of operation he would have on his leg, he chose to stop the treatments at the point when there was no further point in taking them, he tried things—all the medical decisions were made by him, with the support of the medical team, after discussing them with the doctors. Yes, it was a family decision, and yes, we talked about it, and the family does have to be consulted in all of that. However, at the age of 17, he had the capacity to make his own decision.
From spending time with sick children for two years, I saw that illness often brought them additional maturity, a kind of wisdom. There may not be scientific proof of that, but it is based on experience. For some, maturity comes with illness.
At the end, it was Charles' decision. He did not make the decision when he was diagnosed. He did not give up when he was diagnosed or during the treatments. He made that decision right at the end, when he couldn't suffer any longer and he had lost his autonomy and his dignity. If he had been in exactly the same situation but had been three months older, and thus an adult, he could have requested medical assistance in dying. And yet Charles was more mature than many adults who have the right to make that decision.
