Should I visit my terminally ill cousin who lives in the same town?

My relationship with him is only to say hello at extended family gatherings for life events (birth, marriage, funeral). We never socialized and barely had any conversation. Given the family tradition, I will likely attend his funeral, but as he is still in the hospital, it seems odd to not be visitng to say goodbye. I wouldn't know what to say to him if I went except that I am sorry he got sick. He knows he is not getting better since the doctors won't treat him (too sick). Can't even offer a hope that he gets better statement. Would he be annoyed by visitors who he has not relationship with? I don't want to cause him more pain, grief, make him use up his final energy dealing with stranger relations.
