Someone Downloads a Tool from the Internet and Uses It

Someone downloads a tool from the Internet and uses it to experiment with an idea she got from a YouTube video. Another exam you recently passed considers this unethical and inappropriate. A friend of yours just considers this person to be a "script kiddie." You have your own opinions, but what is the most defensive way to respond to this scenario?

A) Lecture the person about ethics and appropriate behavior. Make certain she realizes the trouble she is causing the industry as a whole.
B) Avoid insulting the person, enforce policy in a professional yet objective manner, and consider the idea that this person can be an asset if properly mentored.
C) Explain "Script kiddies are l00s3rs." And agree with your friend that if this l@m3r can't write her own buffer overflow shellcode then she isn't worth a slice of pizza.
D) Shrug your shoulders in indifference and get on with your day knowing your network is so secure that this person poses no possible threat.
