Simple assault does not require threat of death. You have no clue on the contents of the hot sauce and basing your assumptions around that.
You couldn't have just asked for an explanation? WTF? The fact that hot peppers cause inflammation naturally, negates your dependence on it being an allergen. It serves no other perpouse... It was done to irritate, not satiate... The idea that it didn't cause harm, is the antithesis of spiking someone's food even as a prank...English, please? I have no idea what you're saying.
You are questioning the extent he could have gotten hurt, which in context is meaningless. He was charged with simple assault, not even assault or any charge indicating life threatening injuries. That hot sauce could have contained allergens, just like any foreign substance spiked in your food. You are going off on the allergen tangent, not due to the charge in this case... Not for the actual substance used... For nothing, but a completely irrelevant point of the inflammatory reaction to papers not being an allergic reaction. This is the equivalent of "stop punching your self"... Don't spike people's food...
