Should I have not spared this kid??

This naughty kid coughed at my lunch and some other person's
we were all going back home in a conjusted vehicle this naughty kid was sitting beside me and was rowdy and very naughty
When he coughed at my lunch i was so mad he disrespected perfectly good food i was about to throw that same food he coughed at on top of him
But i didn't do it because
A. Throwing food is not nice especially throwing it at someone
B. Also idk why i have this thought he's just a kid

Later my mum also told me why didn't i throw it right then
