Attitude? Check. Short fuse? Check. Proficiency with whatever weapon happens to be near by? Check. Seriously, don't mess with Lisbeth.
That image of her in suspended animation before giving a beat down is now iconic, as is her general badassery. Easily my favourite character in the series.
She killed and maimed her way through 2 movies so there's really nothing left for her to prove. Best course of action: let her live her quiet life because if you give her a reason to seek vengeance, it ain't gonna be pretty.
I don't know if you've ever seen Terminator 2 but that is a friggin gun show. Besides, any woman who can hold her own against robots from the future has my undying respect.
Six words: "Get away from her you bitch!"
