Someone taking no responsibility over it's actions , blaming it's actions , or justifying them , on written words from others . Someone like that will probably not state they killed because of a spell , for they are blind to the spell they are under .

That's right. Someone who kills another person would have to have a precise intention to kill. Nobody says: I, because I am under the spell of words, intend to kill another tomorrow/the next hour because of the spell I am under.

This means that someone who has no willful and knowing intention to kill is not a murderer.
Still, in Germany, we have the saying: ‘Stupidity is no defence against punishment.’

For example, if a woman, because a young, handsome and charming man asks her to quickly bring an important medicine to his grandmother in an old people's home because he is unable to do so and is in a hurry and has to catch a flight because he is urgently needed on an oil rig, and he gives her a hundred euros if she just quickly brings the medicine to his grandmother (which killed her), the woman is also guilty of murder and cannot go unpunished.

She might state that she didn't know that she fulfilled the mans intended kill, but the judge could say that she all too easily accepted the word from a stranger and that she was seduced by a.) his good looks and b.) took one hundred euro.

That's what I meant by an exact situation.
