Just browsing. The murder rate for women vs. men is about 10 to 90%, of murders committed generally, or 15 to 85%, or some other ratio, depending on where you read. Let’s say 10% or better.
The interesting number (1995, FBI Uniform Crime Report): as a percentage of murders of spouses, the ratio is more like 499 to 976.
Do women kill? Yes they do. Spouses, most often. A feminist might look at that number and see women pushed to desperate measures by abusive husbands. Someone else might say that a few of the women that were murdered by their husbands might also have been abusive. But everyone knows, of course, that men are evil.
