It was the acid that did her in. If she shot or even stabbed Sabrina it would have been a different story. Making an acid cocktail seems premeditated.

It's a bit different. I believe she was defending herself, but, who takes the time to make an acid cocktail to defend themselves? If she stabbed her I'd buy it more. I think that woman did harass her but at the same time why would she continue to deal with him?! Let Sabrina have his ass.
