Personally, I think people who have AIDS or any other venereal disease are obligated not to have sex.
This whole debate about condoms is ridiculous. Why should the Church give a license for people to be promiscuous in order to stop the transmission of a disease.
If one willingly passes HIV onto another person could that be considered murder? I think so. Murder is not immediate, but will be slow and painful. Since there is no cure for AIDS then eventually the immune system will break down and the person will die.
