Let's say I've spent years setting up the perfect murder to kill person A. Then, when the time comes, I learn some information that makes me realize I'd rather person B died than person A. Thus, at the last minute, I swap out the murder victim, but use the otherwise detailed murder plan to kill B.
I am clearly a murderer, but was the murder premeditated, because I used a premeditated method, or was it not premeditated since I wasn't planning to kill B until the last minute?
I know transferred intent applies if I was trying to kill A and killed B instead, which would make the murder premeditated. But in this scenario I explicitly changed plans to only target B. I'm not sure if the premeditation for killing A transfers when I never actually followed through with an attempt to kill A.
So, what kind of murderer am I?
