Murder is murder, but only when it's murder. Slaying a dragon terrorizing the town: enacting the will of the town, Lawful. Killing a tiger that looks like it's trying to eat you: self-defense, Neutral. Ordering the assassination of your rival: murder, Evil.
I try to keep things simple. It may not be the way the rules interpret alignment, but it avoids many disputes I've had before enacting it.
I'm curious, because I would have thought invading one's home to loot and kill (admittedly in most cases evil) sentient beings as murder.* which is what most adventures tend to do.
*: I/my group just sidestep this issue following K.I.S.S. as you do.
