that's just a silly conspiracy theory. it certainly is proven that hiv causes aids.
...and with current medication hiv can be kept under control in the majority of cases. if you are hiv positive you still have a bit lower life expectancy though since the medication has side effects.
Teberculosis + HIV = AIDS
Teberculosis + no HIV = Teberculosis
that's also silly. both time it's tuberculosis. there aren't just the same symptoms. you can test for the tuberculosis germ, you know.

but with aids (which also is testable and causes that the immune system doesn't work properly anymore) you can get tuberculosis and other diseases much more easily and they are much harder to treat.
