The King of Pop's former doctor, Conrad Murray, convicted of involuntary manslaughter after giving Michael Jackson a fatal dose of the painkiller, said the singer was "chemically castrated" by his father.

Joe Jackson allegedly was "one of the worst fathers to his children in history," as Jackson confided in him that he had significantly suffered "at the hands of his father."

Michael Jackson, dubbed the King of Pop, led atypical, bizarre life. Even his biggest fans cannot deny that there was something strange about the iconic musician.

One of the most horrifying stories about MJ's childhood is the one of him being "chemically castrated to maintain his high-pitched voice." The alleged castration happened while Jackson was a teenager, and the fear of his father never stopped.

In his book, This Is It! In the Secret Lives of Dr. Conrad Murray and Michael Jackson, Murray wrote what he allegedly learned about Joe Jackson and how he treated not only Michael but the rest of the Jackson family.

The children were not allowed to play, and while in The Jackson's 5, no one was allowed to skip a step. Joe was abusive and would often beat his children.

Michael talked about his childhood, saying it was "really bad:"

"It was more than just a belt — cords, whatever was around.[He'd] throw you up against the wall as hard as you could. He would lose his temper. … I was so fast, he couldn't catch me half the time. But when he would catch me? It was bad."

In another interview, Michael recalled seeing his father and fainting. Throwing up from fear was not uncommon for Micheal, who was the youngest and the most sensitive out of The Jackson 5.

Despite becoming the world's best-selling artist in his teens and maintaining that level of fame despite the turbulence, Michael never stopped being afraid of Joe Jackson.

In 2009, talking to Rabbi Shmuley, Michael said:

"I am scared of my father to this day. My father walked in the room — and God knows I am telling the truth — I have fainted in his presence many times. I have thrown up in his presence because when he comes in the room, and this aura comes, and my stomach starts hurting, and I know I am in trouble."

While the Jackson estate claims that the two made their peace before Michael's death, some sources claim that MJ despised Joe until his death.

Joseph, however, treated his grandchildren better. In one of his final interviews, the King of Pop admitted that his father was different.

"Time and age have changed him, and he sees his grandchildren, and he wants to be a better father. It is almost like the ship has sailed its course, and it is so hard for me to accept this other guy that is not the guy I was raised with. I just wished he had learned that earlier."

Jermain Jackson, Michael's older brother, also said their dad was strict, adding that he never hugged them or even allowed them to call him dad.

MJ confirmed this in an interview, saying he "wanted to call him 'Daddy' so bad." However, he remained Joseph.

Joe Jackson passed away in 2018, nine years and two days after Michael. The life and death of Michael Jackson remain fascinating, scary, and confusing at times. But his musical legacy lives on.

Was keeping his high-pitched voice worth it? We doubt Michael Jackson would agree.
