How would you commit murder ?
You are 100% composed, 83% stylish and 89% intelligent.
You're so slick. You've got this whole murder planned out already, haven't you? Maybe your victim's hurt you in some way - then again, maybe they haven't. Most likely, you're just in the mood for some light amusement. However, this amusement would ensue after much careful planning - you'd be likely to use poison as your weapon of choice, for example, because it's subtle, untraceable (sometimes) and effective.
Have fun - you're the sort of person who is the most likely to get enjoyment out of this, as you're the least likely to be traumatised by, you know, ending someone's life. Just don't get too cocky, or you might not get away with it.
But I am not sure what to get out of this since this actually sounds like me in some elements.
