And you would be mistaken.
Even if a person has HIV, and a high viral load, just getting their blood on you is not enough to contract the disease. Even if you have an open wound, the amount of blood to blood contact needed is very large and extremely unlikely. Fact is, people get HIV through IV drug use and sexual contact, and very rarely through accidental contact with spilled blood.
Combine that with the fact that HIV is no longer considered a fatal disease in medicine, and you would probably be in big trouble for using lethal force in such a scenario.
