Not taking up any of the other arguments because the rest of the Leftist Brigades has done that for me, but I think the problems with your brother's life have very little to do with choice and a lot to do with the inability to make them correctly because of a psychiatric disorder. While what your brother has done is wrong, it is not malevolent - merely pathetic - and should be met with sympathy and compassion, not hatred.

Males with learning disorders often end up in the same situation as your brother. It has very little to do with laziness and everything to do with poor decision making because the faculties available to you and I to make those decisions are not available to him.
