r/masskillers

For example, I never subscribed to when people say, "Mohamed Atta (the 9/11 ringleader) was always suicidal (but knew that taking your own life is 'haram' in Islam) and he was looking for a way to die, and committing 9/11 was his way to do so." I really just believe Atta decided he was prepared to die upon deciding he wanted to be a "martyr" for Islam.

It reminds me of when people say: "Dylan Klebold wanted to die, and didn't care if that meant he had to kill people, and Eric Harris wanted to kill people, and didn't care if that meant he had to die."

On the 19th of December, 2025, 27-year-old Chang Wen went on a stabbing spree at the Taipei Main Station (seen here) and later at a Eslite Shopping Center. He committed suicide by jumping off the roof of the building. He was a copycat criminal who was motivated be the 2014 Taipei Metro Stabbing which left 4 dead and 24 others injured.

This video isn't nearly as graphic as most other videos with this flair but I still think it's the most fitting.

Usual age for female mass shooters 20s-40

 Most of them seem to take place on the West Coast and East Coast of America with the few exceptions being in the middle. Most female mass shooters suffer from mental health problems. Any other female shooter I miss? 

What comes to mind for me is the mortuary temple of Hatshepsut in Egypt. in 1997 Islamic extremists killed 62 people (58 of whom were tourists) with automatic rifles and cleavers.

the 8 attackers committed suicide soon after the attack.

I think its one of the most horrific attacks in history, because just imagine being chased through those tight, dark, ancient halls. with armed terrorists chasing you.

Ra cried that day from the brutality of it...

She would be turning 20, but instead she’ll always be 6 happy birthday, Jessica!

For me it’s Randy Stair. For someone who didn’t believe in God and actively mocked religion, he also believed that he would be reincarnated as a ghost girl from his OC character squad he created after his massacre. So many lives lost because of this schizophrenic weirdo…

This and many other photos and video prove that the guns were not properly locked away.

Not condoning his actions or saying it justifies, but it’s how they bullied him

In Cruel Twists of fates these people survived mass shootings to later die in other shootings.

Survivors of the Columbine High School Massacre, They were later shot and killed at a Subway in Littleton Colorado just a short distance from the school. As of 2026, the case is still cold. I think it was also said that Rachel Scott worked at the same subway the couple was killed in.

Jessica Ghawi

Any other survivors who were killed or survive other mass shootings?

She would be turning 15, but she’ll always be 11, happy birthday, Maranda!

I personally don’t know if he would/wouldn’t do it again.

The only mass gas attacks I know of are the Tokyo Subway attack and the Midwest Furfest attack. Are there any other prominent attacks that used toxic gas?

I assume the lack of dangerous gas attacks is simply because it's more time consuming to make than a simple explosive and wouldn't be as deadly as a bomb or gun.
