If you're really that hung up on semantics. Most states classify what used to be called manslaughter as criminally negligent homicide.
IT's not the semantics that I am hung up on. It's the fact that people who kill other people are killers - particularly when they made the decision that resulted in the death.
If a family member is shot to death in a robbery attempt, are they any more dead than the family member killed by a repeat offender drunk driver? No. And both hypothetical dead people were killed by someone's DECISION. And in my opinion (not worth much, apparently) both are murderers who deserve the maximum.
