Good heavens, no! Silly question, isn't it? If you look back at our own youth, any of us who are honest will admit to doing things that were silly, even illegal, in our attempts to be "cool". Would that have justified someone shooting us, just because our then-present behavior might have led to a less-than-perfect adulthood?
The only reason to shoot anybody is to stop the immediate and otherwise unavoidable threat they are offering to your own life and/or health. Anything else is too ghastly to contemplate.
