Is there such thing as premeditated self defense charges?

I remember one time I was on the road and some road rager was following me and he stopped when he saw I was driving into an alleyway, long story short I was gonna shoot him in the alleyway, well that would be worse case, I would probably see if they were armed in any way but if I did shoot him, would the fact that I premeditated it by leading him into an alley show up on my charges if I would have gotten a murder charge, if they weren't armed for example, or would it be a man slaughter charge?

There was also another time I was being followed again but it was around midnight, so I drove to a dark residential road and parked my car turned off my rear and headlights and left on the emergency lights in the middle of the road just blocking the road, it was a small road, I saw the car start driving into the road but then reversed back into the intersection and drove off in the other direction, this car had tinted windows so I was unaware of what they had and how many they were, my plan was to leave my car in the dark and reposition myself so when they go behind my car I can maybe I can see what they are up too and worse case I'll shoot at them from an unexpected location outside the car, again I think this is another example of premeditation self defense in a way, even tho it's more offense than defense if you truly think of it, I wanna know if I can do this cause third is the charm or whatnot and it will probably be the time I'll have to actually act so to be ready and what i call a defense strategy might be a crime in the eyes of the court.
