I agree with those who have said that you should not give it to your brother, and if he doesn't know about it, all the better. Someone will treasure that quilt, and for him, it could only be a painful reminder. See what he has in mind to do next, and maybe you can make a quilt that's appropriate, or how about asking if he has a bunch of old t-shirts that he's kept for sentimental reasons and making him a t-shirt quilt that will help to remind him that he has had other interests and strengths and connections in life aside from this one goal that has been taken from him.
