Here's some additional information. :)
(First-Degree and Second-Degree go under the same category, I just want to evaluate more on the subject.)
First-Degree Murder: Crimes in which the offender planned to kill another person and carried out the act. Described as “malice aforethought” or premeditated murder. For example, a kill with malice.
Second-Degree Murder: Homicide in which the offender meant to physically hurt the victim, but did not mean to kill the victim.
Manslaughter: Homicide that is considered less blameworthy than others. Contains Voluntary manslaughter (murder committed during intense emotion) and Involuntary manslaughter (killing due to reckless behavior or acts). For example, the killing of a child due to the parent shaking it.
