Please consider applying the correct word to the context you wish to discuss.
Getting pretty deep in the semantic weeds here though, and I feel obliged to say I have no horse in this race either way. Don't kill or murder me :)
Please consider using the correct definitions of words when telling others to "please consider applying the correct word".
The fact that people keep talking about gun ownership in Texas like it's a deterrent is odd. It's not like the criminals don't have weapons too.
IANAL, but I don't believe murder can only be if it's premeditated. In fact, IIUC, most murders are not premeditated.
Some examples:
Felony murder: https://en.wikipedia.org/wiki/Felony_murder_rule
Depraved indifference: https://en.wikipedia.org/wiki/Depraved-heart_murder
Murder without premeditation: https://www.floridatoday.com/story/news/crime/2019/11/20/kal...
I'm sure there are many other examples.
Murder is the unlawful killing of another.
Homicide is human death by the hands of another human.
Murder is a legal term.
