What's the best part of blowing your brains out with a shotgun? The satisfaction of knowing your wife will spend tomorrow having to scrub pieces of brain off the drywall.
I'm not sure what you're saying, are you making a joke about suicide?
Yes, I would do it to punish my wife.
Suicide is a very serious subject and not something to do to spite someone. You shouldn't feel satisfaction that your wife you have to clean up the aftermath of your suicide. How would you feel if this happened to you?
