You have to talk her out of it, instead of showing her respect on her level and punching her out of it (She's young and tough - she'll heal. And probably prefer the lesson in humility given her way than condescendingly talked down to like the child she actually is). I was annoyed that it was impossible to help Lars grow a backbone.
On topic - Respect for Life is a "Good" trait. Lacking that means you're Not Good. It doesn't necessarily mean you're Evil (Though it can)
And, I never said "Burn a child to death" - merely "Set one on fire" - which, at first, envisioned as igniting an article of clothing or hair (Richard ****head gets ALL his clothes and hair ignited for being a monster - he'll still live). Unless the kids in question are pickpockets/thieves, when it's Explosive Runes all the way.
