The Children Act

I just saw the movie "The Children Act" 2018 about a child who didn't want to take a transfusion because he and his parents were Jehovah Witnesses. But the judge ruled against them, and he was cured. When his cancer came back, in the hospital he refused the transfusion because now he was 18. But he did not believe in the god of JW's. The reason he wanted to let himself die was because of how he felt that his parents didn't want to save him and to just let him die without a transfusion. What kind of love is that? I assume he is feeling.
