Explain how someone could show more compassion towards a family member who is struggling and why ignoring their problems could lead to regret later on.
If you gave one rats ass about your brother you would drag him into your home and not post BS here full of excuses. Next when he is dead, you will post, I wish I really gave  a rats ass to put up with him and took a stand and the effort to give him a chance despite the problem it would cause me.  Don't like it, then feel the suck.
