It's the Menendez Brothers, they faced abuse and sexual assault from both mom and dad, and no one helped them, and their only choice was to kill them since their dad threatened to kill them if someone will find out about what cruel things he had done to them.

Here's some information about Menendez Brothers:

Joseph Lyle Menéndez (born January 10, 1968) and Erik Galen Menéndez (born November 27, 1970) are American brothers who were convicted in 1996 for the murders of their parents, José and Mary ("Kitty") Menéndez.

Lyle and Erik's father, Jose Enrique Menendez, was born on May 6, 1944, in Havana, Cuba. At age 16, he moved to the United States, shortly after the beginning of the Cuban Revolution. Jose attended Southern Illinois University, where he met Mary Louise "Kitty" Andersen (1941–1989). They married in 1963 and moved to New York City, where Jose earned an accounting degree from Queens College.The couple's first son, Joseph Lyle Menendez, who goes by his middle name, was born on January 10, 1968.

Kitty quit her teaching job after Lyle was born, and the family moved to New Jersey, where Erik was born on November 27, 1970, in Gloucester Township.In New Jersey, the family lived in Hopewell Township in Mercer County, and both brothers attended Princeton Day School.In 1986, Jose's career as a corporate executive took the family to Beverly Hills, California.The following year, Erik began attending high school at Beverly Hills High, where he earned average grades and displayed a remarkable talent for tennis, ranking 44th in the United States for 18-and-under players.

And despite the fact that they were victims, the USA justice system labelled them as Killers and gave them life sentence without a possibility of parole. To this day they are separated both in prison, and villified by people who think that Menendez Brothers were faking the story of abuse and sexual harassment just to get a pathetic pity while what they were saying is true and they had all the evidence to justify their action, since it was clearly a self-defence.

Many people across the world ask for justice for Menendez Brothers and that they need to be free, and this men's day, I want to remind everyone that they are victims, they had to do it and that it's not their fault that they went through years and year of sexual abuse and no one believed them, nor got concerned about them or their mental well being.
