Interesting thought. If there were threat of arrest/jail time, I would make damn sure I succeeded - I've always thought about it in that way, anyway, though. It's a final act, and not one I would want to attempt unsuccessfully.
On the other hand, I am intrigued by the idea of fining your 'estate' - so to speak - if you were 'successful' in your attempt. One of the things that keeps me from acting on my impulses is the thought of my kids having to deal with it. I've spent time figuring how many years until I don't have to worry about that screwing up their education, etc. If there were a serious financial repercussion to my kids or husband as a result of that act, it would probably actually deter me even more. The challenge there, of course, is that it would make me feel even more powerless, even more like I'm required to act and behave in a way that serves others, regardless of how painful that is to me.
I might not be the best barometer for realistic responses to this type of proposition, at least from the point of view of society.
