Are criminals born that way, or does life create them?

In this episode of Killing Time with Friends, Billy, Melanie, and Hope explore one of the biggest questions in psychology and criminology: Nature vs. Nurture.

We dive into brain science, trauma, genetics, and real criminal cases to explore how violent behavior develops. From the shocking story of Phineas Gage to the controversial twin separation studies, we look at the science behind personality, impulse control, and behavior.

We also examine well-known criminals like Aaron Hernandez, Ted Bundy, Jeffrey Dahmer, and Richard Ramirez to ask whether their crimes were influenced more by biology, upbringing, or a complex mix of both.

By the end of the episode, we ask a difficult question:
Are killers created… or discovered?

This episode explores the psychology behind crime while emphasizing the importance of mental health awareness and early intervention.

Listen, think, and decide for yourself.

A tragic school shooting in Georgia left four people dead and many others injured. But the trial that followed raised an even bigger legal question.

Should a parent be criminally responsible for the actions of their child?

In this episode of Killing Time With Friends, Billy, Melanie, and Hope break down the case of Colin Gray, the father of the Apalachee High School shooter. Prosecutors argued that by failing to secure firearms and ignoring warning signs, Gray created the conditions that led to the attack.

But the debate isn’t that simple.

Was this criminal negligence, or is the law being stretched beyond its limits?

The hosts examine:

• The timeline leading up to the shooting
• Warning signs that may have been missed
• The role of schools and mental health support
• The legal arguments behind the charges
• Whether the verdict sets a dangerous precedent

This episode includes a respectful discussion honoring the victims while exploring the difficult legal and ethical questions surrounding parental responsibility.

We also want to hear your perspective.

Do you believe the verdict was justified ... or does it open the door to criminalizing bad parenting?

In December 1968, 20-year-old Emory University student Barbara Mackle was kidnapped from a motel in the Atlanta area and buried alive inside a fiberglass box underground.

She had seven days of air.

For 83 terrifying hours, no one knew if she would survive.

But this story doesn’t end with her rescue.

The man responsible - Gary Steven Krist - served his sentence, reinvented himself, and decades later became a licensed physician. Until he was arrested again… this time for running an underground cocaine lab.

Three friends. Dark cases. Real questions.
