Why people commit murder instead of divorce

Psychopaths. It's often about money and in many cases because even if the killer was the one to intiate divorce they don't want their partner to be happy with anyone else. Same reason why it can be dangerous to leave an abusive relationship.

They can’t handle a divorce because they know she’d take him to the cleaners. They’re so blinded by rage, that they take the chance on getting away with murder.

They're mentally unstable. They've most likely always been. Most of these people are psychopaths who don't even care even after they do it.

Like WeirdGuy says, it's often about money. Sometimes an insurance policy, sometimes savings and other assets, sometimes being pissed off at the idea of having to pay support.

There are also people - almost always men - who murder their spouse or partner when she says she's leaving him because he feels he owns her, and she doesn't have the right to leave him or be with someone else.

Many reasons, some people will become homeless without a spouse.

This is a really dumb question.

Different reasons but almost always its about money. This is why you should stash some of your money away just incase.
