Foids don't feel fear and pain in the same way that we do.
They are aroused and excited by it.
You underestimate how stupidly the foid brain has evolved to enjoy domination, fear, and submission.
Positron emission tomography has shown that reward pathways become activated in foids in response to pain and fear stimuli, whereas only logical areas of the brain activate for males.
Carfentanil is released in far greater amounts in the foid brain to negative sensations and pain, and their mu-opioid receptors activate to a far greater extent than male, creating a rush of pleasure like heroin.
Foids love feeling outrage, sadness, and anger. They love feeling pain, fear, and domination. They experience orgasms while giving birth and being fucked by large objects, both things that damage the body.
The foid brain is very maladapted and strange. It's irrational in the realm of pain and pleasure.
It's very possible that a foid may enjoy being killed violently.
Pain actually activates mu-opioid receptors in the human brain and releases carfentinil, but it does so in different areas for the male and female's brain. In the female, it is more connected with the reward pathways than the male's, where the receptors are activated in the logic-processing centers.
The beta endorphins released by pain are also regulated by estrogen, which magnifies its effect, whereas testosterone has no such effect. This acts like a heroin high.
A good percentage of women have experienced orgasm while under great pain, such as during childbirth. Also, when they are being fucked by horses, which damages their body to a great extent. So there is a real (maladaptive) connection between pain and pleasure for them.
It's not like the male where pain is just a net negative.
For the foid being murdered, it would be "painful" in a sense, but feelings of pleasure may overtake the pain to the point of orgasm.
