Knowing what she was doing doesn't make it premeditated though, the point is whether or not she planned the attack beforehand, or if it was a reaction to the situation she walked in on, and does the extremity of that situation justify her reaction.

Personally I think it does. I reckon my parents would have done the same thing, and I think I would probably react the same if I was a parent. This is a peodophile in the middle of raping your child, you'd want to attack them with everything you've got to get them to stop, and if she had a pocket knife on her then I can completely understand why she'd use it. Her only priority in that situation would be saving her child, I don't think it's reasonable to expect anyone to show restraint.
Premeditated would be if she'd have done nothing, left and calmed down, then planned to attack him later.

The fact as well that she called the police straight after works against the idea it was a premeditated attack.
