1. She murdered her abusive husband

“I used to help out at a nursing home. This old Russian lady would relate the same tale over and over. Her husband drank and hit her. It was sad for sure. But one day she leaned over and whispered, ‘He was asshole drunk, so I pushed him down stairs. Dead.'” — PowerWordCoffee

2. He encouraged depressed people to commit suicide

“Told me that he used to go on forums and boards dedicated to people struggle with depression, and he’d PM the ones who were feeling suicidal with instructions on how to go about killing themselves, and give encouragement to do so.

I’ve never lost so much respect for a person within the duration of a couple minutes.” — JohnBoddy

3. He planned to murder his ex-wife’s new boyfriend

“A customer of mine told me he had planned the kidnap and murder of his ex-wife’s new partner. He had even bought all the supplies he needed to carry out the plan. His intent was to douse him in petrol and burn him alive…” — uncle_monty

4. She was in love with her brother

“A colleague confessed that she had sex with her brother throughout her childhood and early adolescence. She also told me she despises her brother’s wife because she is in love with her brother and is insanely jealous of his life and kids. She has never had a relationship and fears she will never be married or have kids of her own.” — Keystoner

5. She killed her best friend

“‘I killed my best friend by accident while high on cocaine, one year ago.’ She was also my girlfriend.” — DaMisterO

6. They raped innocent children

“I used to investigate child abuse. People would sit down and tell me about their day, and their finances, and their car troubles, and their bad knee, and how they raped a four-year-old because she was leading them on and don’t you think 4-year-olds are getting way too sexy nowadays — all in one conversation.

Sometimes you could forget who you were talking to and part of you would think this person seems alright, and then you realize that’s how they went unnoticed for so long.” — effieokay

7. He used to sleep with his underage students

“I was having a few beers with another (much older) teacher, he told me he used to sleep with thirteen-year-olds when he was 30 and living in his hometown.” — [deleted]

8. My father was raped and then became a rapist

“That would definitely be when my father drove 2000 miles to my home to sit down and for the first time be brazenly open about how he was raped by his cousin when he was 12 and how he has been a pedophile since, but its okay, because he was raped as a child and, hey, turned out okay.

This comes out of the woodwork as he was preparing for trial because he volunteered his computer to the police and it had kiddie porn on it.

His trial is in March.” — SonofBadDad
