Definition & Meaning of Second-Degree Murder
Second-degree murder is a serious crime. It happens when someone kills another person without planning it, but still has intent, malice, or knows their actions could cause death.
Key points:
- The killing is not planned.
- The person acts with malice—meaning they know their actions are dangerous.
- It is more serious than manslaughter, but less serious than first-degree murder.
Simple examples:
- A person gets angry during a fight and kills someone. They didn’t plan to kill, but acted with deadly intent.
- Someone fires a gun into a crowd “without caring who gets hurt.”
Short dialogue example:
Friend 1: “Is second-degree murder planned?”
Friend 2: “No. It’s intentional, but not planned.”
Background & History
The idea of second-degree murder comes from older legal systems that wanted to separate:
- planned killings
- emotional or impulsive killings
- accidental killings
Before these categories existed, all unlawful killings were treated the same. Over time, courts realized not all murders are equal. So the “degree system” was created to make punishments fairer.
Different countries and U.S. states use this system with small variations. Some places even have no second-degree category, while others define it very clearly in their criminal codes.
The main goal has always been to judge each killing by intent, planning, and danger to others.
