Seasoned homicide investigator claims that sexually successful men are more likely to murder/harm women over rejection and handle rejection very poorly. Does this line up with your observations? Why does this occur so much if a man has options?

So last night I was watching this true crime series where they have the chief investigator of the cases themselves do the voice over narration and give personal input/comments throughout. The one I watched had an investigator who had worked hundreds upon hundreds of homicide cases.

Something he said about one case was interesting to me. In all of his hundreds of cases he's worked on, he claims that he has found that men who he says "have lots of women" or as he calls them, "sweet talkers" or "players," in other words sexually successful men, are more likely than other men to murder or assault women, particularly because of rejection.

In this specific case, when they looked into the murdered woman's friends and contacts, they found that one man she had dated had many many women in his life, and apparently that alone was enough for this investigator to put him on top of the suspect list, greater than the other men she had been involved with, who were more normal men - even though she was less close to the more successful man than the others.

He ended up being correct - the man, despite having well over a dozen women, shot her in the back of the head because, they believe, the victim tried to break up with him. He even had one of his side pieces help him clean up the scene and cover for him.

Additionally, this man wasn't a "thug" type of player - he was wealthy and successful in career, had a very nice large home, educated, no violent history etc. The victim also was not his youngest woman or particularly valuable over the others.

The investigator claims that these men get more upset over rejection or being dumped than most men, because they feel insulted that a woman might not want them. Obviously this doesn't often manifest as murder, but the claim is they are also much more likely to rape and assault women and generally "react more violently" over rejection or being dumped.

From my friends who are club goers and regularly deal with these types of men, and general testimonies of women, they've attested to the same - that men who seem more confident or like "players" handle rejection much worse, while shy, "beta" guys tend to accept it.

However, if these men have tons of women available, the usual idea would be they're too apathetic to care because they can just go to the next woman. If a man has abundance, he won't care about one girl. But the real world seems to contradict this.

To women - does this match up with what you experience? Do more attractive/seemingly sexually successful men handle rejection worse? Have you ever felt you were in genuine danger over rejecting or dumping a man, if so what type was he?

Why would this occur? If the man had many women available, why does one rejection bother him enough to do this, or generally have such strong negative reactions - pride, entitlement, fragile masculinity, etc?

Edit: "women choose them" is not a valid response and doesn't answer the question y'all gotta come up with something relevant, I believe in you, you can do it
