How can serial killers take lives and hunt other humans and not give a fuck?

Anonymous
I had been looking at a couple videos on YouTube and I ran across videos of Jeffrey dahmer , Richard Ramirez and a few other serial killers and it’s like they just didn’t give a fuck. In the interviews they seemed like normal regular people so you never would think of them killing other people. Did they have personality disorder where they just turned into to completely different people in those situations? I was diagnosed with anti personality disorder but I could never see myself killing anyone unless threatened. Do any of you think Dylan klebold and Eric Harris would have been capable of being serial killers?
