What drives someone to commit a crime? Why do people kill? If we remove revenge murders and acts of self-defense (justified), there are 2 primary reasons why people kill. The first is that killers crave the feeling they get when they commit the crime. It is irreplaceable to any other feeling. One that normal people like you and I will never understand. This is why killers attempt to rearrange the crime scene or take objects with them so they can recreate the memory. The second is that they can't control the triggers that drive them to kill. They act with no thought or remorse. It's an insatiable feeling that grows and grows. It's similar to a high for a drug addict. They chase it to relive the rush from the first encounter, but sadly, they will never be able to.

Other less significant external factors also drive crimes. This includes economic environments, substance addiction and abuse, dysfunctional families, mental disorders, or trauma. According to the FBI, violent crimes occur every 25 seconds and murders every 31 minutes in the United States.

The scariest crimes are those done in an act of randomness. When a perpetrator kills someone he doesn't know without rhyme or reason, it's horrific. It's horrific because we will never be able to find the motive. We or the victim will rarely ever see it coming. These are the hardest to predict or understand. Random acts of murder occur the most among innocent young women.

Text Me When You Get Home is an excellent true-crime docuseries. It showcases the stories of innocent women who were abducted or killed in the digital age. Many of the cases were shockingly about a perpetrator who did not know his victim. The women were randomly targeted. Text messages and digital footprints were the main sources of catching the killer.

Evil exists, and it comes in all shapes and sizes. Very often it's the least likely people who commit gruesome murders. Our friends, family, neighbors, all could be killers. Normal people who know what they are doing is wrong and could face severe punishment choose to still go through with it; it tells us the feeling is greater than the risk. To them, it's not a risk; it's a mindset and rewarding justification that drives them repeatedly.
