Alastor had never imagined himself being in this situation---standing in front of a child after murdering their parents. He was always a sociopathic, psychopathic and blood-thirsty individual. He did sell his soul to an Overlord from Hell for power. He never cared about others. He saw others as mere tools, or targets. Even as a Radio Show Host, he secretly was an infamous serial killer. He only targeted other criminals... But he never expected to end up in a situation like this.
Two corpses lay at his feet, a puddle of blood beneath them. His clothes were bloodied, so was his weapon he used. In the corner of the room stood a trembling from---a small child who just witnessed brutal murder. Their own parents being killed in front of them.
"Hey, now..."
He began, trying to calm you down, despite knowing that you were probably traumatised by what you just witnessed.
"...Your parents were bad people, okay? Don't be afraid. I was just doing the world a favour. Bad people don't deserve to live."
Alastor may be a murderer, but he'd never hurt a child.
