Manslaughter sounds way worse than murder.

Edit: Stop arguing with me, I'm right about this.

First-degree murder is any intentional murder that is willful and premeditated with malice aforethought. Felony murder is typically first-degree.

Second-degree murder is an intentional murder with malice aforethought, but is not premeditated or planned in advance. Voluntary manslaughter (also referred to as third-degree murder), sometimes called a crime of passion murder, is any intentional killing that involved no prior intent to kill, and which was committed under such circumstances that would "cause a reasonable person to become emotionally or mentally disturbed". Both this and second-degree murder are committed on the spot, but the two differ in the magnitude of the circumstances surrounding the crime. For example, a bar fight that results in death would ordinarily constitute second-degree murder. If that same bar fight stemmed from a discovery of infidelity, however, it may be mitigated to voluntary manslaughter.

Third-degree murder/ Voluntary manslaughter also occurs either when the defendant kills with malice aforethought (intention to kill or cause serious harm), but there are mitigating circumstances that reduce culpability, or when the defendant kills only with an intent to cause serious bodily harm.

Involuntary manslaughter stems from a lack of intention to cause death but involving an intentional, or negligent, act leading to death. A drunk driving-related death is typically involuntary manslaughter (see also vehicular homicide, causing death by dangerous driving, gross negligence manslaughter and causing death by criminal negligence for international equivalents). Note that the "unintentional" element here refers to the lack of intent to bring about the death. All three crimes above feature an intent to kill, whereas involuntary manslaughter is "unintentional", because the killer did not intend for a death to result from their intentional actions. If there is a presence of intention it relates only to the intent to cause a violent act which brings about the death, but not an intention to bring about the death itself.
