"I intend on striking him down every time he puts another individual is in danger, Master Kenobi."

Qui-Gon's retort came out a bit (a lot) snippier than he wanted, but the fact that he'd meant to throw some less-than-friendly sass in there in the first place spoke volumes on how he felt about the situation. Sarcasm, no matter how dilute, was never meant to be a tool for anything less than invective intent. The use of Obi-Wan's title instead of his name drew familial distance between the two, in turn.

"If he is no danger to anyone else, as you've said, then your objections won't be necessary."
