I have been directly and peripherally involved in investigating a few, "crimes of passion." In some cases the children are viewed as possessions in a, "If I can't have them, she won't either." Sad. Very sad.
Yes, people who kill themselves seem to often get a “I’ll take the kids with me” notion. Hopefully though the children don’t end up where their murderer does.
Yeah but if you killed the wife, she won’t get them.
I think it is more of “If I can’t have them, no one can have them”. I had a relative like that.
