Marriage is the only relationship in your entire life thats governed by a legally binding contract that requires court orders and lawyers and expense and a great deal of fannying about to get out of. Not everyone can be bothered with the red tape, and the more sociopathic (or desperate) someone is, the more they might consider a homicidal alternative to divorce. Say your other half is rich and you're broke, and completely amoral or say they've Done You Wrong, and this time was the last of a thousand straws. Well, murdering your spouse isnt like killing anyone else. Marriage is the only relationship in your life that, by definition, involves just two people. Most relationships are webs, patterns of connection that link people but a marriage is just the two of you.
