Can I just say - apart from this being a theoretical discussion - I'm not willing to inflict serious or fatal injury either.
I think trying to killing someone in *any* way is just as bad as every other way...in my opinion. I say 'in my opinion', but if we were talking about this in terms of real world acts, it is absolutely not a thing that the vast majority of people would tolerate, not to mention illegal everywhere. I can't myself see how it is any more acceptable a thing to want to achieve it by paranormal means, as if that makes it somehow less bad, less severe or more acceptable.
In terms of a 'philosophical' discussion...
...people do get killed by other people and have been since before history began and yes I know our cultures are fascinated with it, as seen in endless tv, film and books about murder and killing. I consume a lot of that kind of fiction.
But...I think my ethical standards should not change when I take paranormal action from what they are when I act 'in the real world'.
Don’t be scared. This island is full of noises, strange sounds and sweet melodies that make you feel good and don’t hurt anyone. Sometimes I hear a thousand twanging instruments hum at my ears, and sometimes voices that send me back to sleep even if I had just woken up—and then I dreamed of clouds opening up and dropping such riches on me that when I woke up, I cried because I wanted to dream again. Caliban, The Tempest, Shakespeare
