It is very dangerous to become invisible by spraying \(T^{-}\) particles onto the body. Any small \(T^{+}\) source like a cigarette bud, a lighter fire, or any hot surface will cause a flow of \(T^{-}\) particles away from the body. This high current of charged particles "electrocutes" the person instantly.
Besides, invisibility provided by \(T^{-}\) particles is detectable by infra-red and shows up as white washed region of very cold temperature.
Suicidal Assassin you are not.
