Yeah, that's what I meant; for his style, this is the norm. In his universe, her killing the guy or not is 50-50. I just appreciate that, unlike the MCU, something horrible happens and it's 50-50 someone makes a quip. I think the former has a more consistent tone, while the latter can severely undercut whatever is happening.
That said, I did think it was overkill lol. She could've killed him, by speedblitzing him when he had to reload.
