Incels. Involutary celibates. Aren't getting any so want to rape and murder women, because of course it's our fault. This guy and the whole of the muslim males.

It’s impossible to formulate a single reason that accurately and thoroughly describes all reasons why any particular man may grow to hate and kill a woman. Honor killings, Jack the Ripper-style deviance, land or other property disputes, “the heat of war” as in Mai Lai, etc. The common theme is a lack of respect and empathy for the other.

A specific killing of men would probably be 'androcide,' going by the typical use of... erm, is it Latin or Greek... can't remember--ennyhoo, it's better to use 'homicide,' in my opinion, as separation of gender in this case may lead to dehumanisation of one or the other.

As to why they do this? They're shitty human beings, that's why. I don't care what their past was like. I hate this kid-glove treatment of abusers and bullies and murderers that other people are propagating. I had a terrible relationship with my mother, I couldn't get a date (much less sex) if my life depended on it, but I'm not going to be so stupid and evil-minded as to blame women for it.

Horrific. I read about this one and saw on the news. There really are no words to describe the horror and insanity, and evil. Evil is still a good word sometimes, religion or none, for actions like this, for someone like this. Mutant is another good description I use for people like this.
We live in a most wonderful time in many ways but there's this awful sick violent destruction going on also. Strangely imilar to the Dickens opening, "It was the worst of times, it was the best of times", hard to wrap the brain around this rot... Sorry I don't have something more pithy and wise;
"..It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us..."

I wonder what sort of relationship he had with his mother. Mothers can be evil and violent or they can be sick with mental health problems which deprived their son of love and nurture. CPTSS can have devastating effects later in life

There are many messed up humans like serial killers that often focus on woman like say the green river killer or jack the ripper or the Yorkshire Ripper. women rightly or wrongly are always vulnerable to men from birth till death. there aren't many serial killers that are women let alone ones that kill only women. sad but true.

I don't know what brings a man to hate women enough to kill them. However, sex is glorified (imo) to the extent that not having sex or being a virgin is stigmatized, especially for men. Apparently, the okcupid data showed that 50%of the women on the site who responded to the survey said that they wouldn't date a virgin man. I will try and find a source for this. Further, entertainment industry propagates such ideas as well.
Whenever such horrific crimes occur, people blame the perpetrators entirely. I think, we as a society shouldn't be so quick to give ourselves the clean chit.

Murder is terrible....no matter who you murder.

I learned the word femicide a few weeks ago. It's like gender apartheid.

He thinks he’s entitled and can’t understand how or why women won’t be sexually intimate with him. He blames them when it is his fault.

It's really nothing new. Remember Jack the Ripper, Ted Bundy, and The Green River Killer?

We don't need protectors; we need equality. Worst of all, he probably hates women so much because none would shag him.

I'm with you. I don't understand it. It makes no sense.
