Cheating can destroy a person. Leaving them feeling worthless and unable to trust anyone. I'm not saying beat your girl or cut off your man's dick, I'm saying they deserve it in some sense. If they're willing to emotionally harm someone and take away that person's love...they have to expect some sort of punishment. Whether it's taking the kids or -blam!-ing their BFF...maybe even damaging property. A lot of people cannot handle the stress of a sudden broken heart. :)
