Since we never heard of her killing anyone since joining Fairy Tail, I'd say we can savely assume that she doesn't have killing intent either. And we can also say that she has a lot of skill if she manages to KO people without killing them or cutting off limbs or such even though she uses swords.

But I guess the same goes for other people who manage to burn, freeze, zap or otherwise attack people with potentially lethal magic without causing death or permanent damage to their opponents.
