Your immune system is basically running a tiny mafia operation inside your body. The virus thinks it's slick, hijacking innocent cells like some microscopic carjacker. Then the helper T cell spots this crime and calls in the cytotoxic T cell—the biological equivalent of that friend who's way too eager to fight someone at a party.
Next thing you know, cytotoxic T cells are executing infected cells with zero remorse while the virus is like "wait, this wasn't in the brochure." Meanwhile, helper T cells stand back watching like proud crime bosses who didn't get their hands dirty.
Nature didn't create an immune system—it created a hit squad with advanced degrees in molecular biology.
