Yes, that's called a woman fighting for her life. If he is killing her because she rejected him or left him, I don't understand you trying to somehow spread the blame to her.
Its because I have heard the actual facts. In interview rooms, hearing rooms and trials. And it is almost never how you think it is. Women want to think it is their rejection alone that “breaks his heart.”
You just don’t know how messy it is.
Tell you what: Make a list of all of the nasty evil combative deceitful things two people can do to each other. Then write come anecdotes, like:
“she slapped him in the face in front of the kids” or
“She let’s the new boyfriend beat his son” or
“the daughter may be being abused” or
“she got him fired (arrested) by lying about spousal abuse”
or
“she’s a drunken slut” or
“her new BF beat the Hell out of him”
Then assume most of those apply when it comes to a death. Because they do.
