It is my understanding in the US that the charge of murder has to do with being planned; self-defense would probably fall under some form of manslaughter
Involuntary manslaughter usually or criminal neglegence but not murder
No. Most commonly (differing terminology may be used) it is self defense. As in you were forced to kill the other person with ABSOLUTELY no alternative whatsoever. Them or you. E.g. A cop shooting a man that fires a gun at them, misses, keeps coming screaming '******* die pigs!' and looking at them hatefully. Bang. Self defense.
If I go into a bar, get drunk and (accidentally) hit someone on the way home with my car, it is Involuntary Manslaughter.
If I stayed in the bar, got even drunker and beat someone to death in a drunken rage, that is Second Degree Murder.
If I make detailed plans to kill my neighbor, sleep on it, think about it some more, then perfectly execute my plan. That is First Degree murder.
In reality it is never that clear cut. Was the burglar armed? Was he shot in the back whilst fleeing? Was he incapacitated before being shot? E.t.c.
If you kill someone no matter what it is murder. IN the legal sense for punishment reasons it could be "labeled" something else depending on evidence and the surrounding circumstances of each case.
No, but be sure it is truly self defense. It you have the opportunity to run away and instead choose to kill the other person, that is NOT self defense.
Yes, killing a person is murder no matter why.
But don't worry,
if it's in self defense,
you will be forgiven...
No, right of self-defense is almost universally recognized.
No...we have the right to life.
