Tactic for Peace: Would you scare for peace?

My fiance and I are currently reading a book entitled "Emigrants" By Vilhelm Moberg, and a part of the book got me to thinking about peace and tactics,in the book a farmer named Jonas Petter had his wife help him sharpen a knife on a sharpening stone,and he used this tactic to make her believe that either her own life or the life of her husband,Jonas,was in danger,aka he was to kill her or commit suicide,he then went inside the house as he was outside sharpening the knife,his wife stayed outside as she fainted from sheer exhaustion from helping her husband sharpen the knife by turning the crank on the stone,and all the while she was wondering why he needed the butchering knife so sharp,since they did not need to butcher any animals for several months,this went on for thirty minutes,Jonas Petter put the knife he had sharpened on the mantle inside where his wife then found it after recovering from exhaustion,his wife hid it from him in the barn where she thought he would never find it,while Jonas was in the attic preparing an "American Chest" as he was journeying to America,he stayed up in the attic for a while because he wished to worry her as she had no idea where he was,and after he came down and saw the knife was missing he knew his tactic had worked,and that his wife would now give him peace for the three weeks left before his journeys,so to the questions,Have you ever used a tactic,maybe not as such,but one to get peace?If so,what was this tactic and why did you use it?On whom?Did you regret using this tactic?Did your tactic work?If not,did you use another tactic?I am not sure if I have ever used such a tactic though there is one instant where two of my friends were at my parents house and they were arguing and one friend was threatening to hurt the other over some rumors that had been spread,so I brought out my bebe gun to keep the peace,and I shot the one friend that was leaving in the side,to scare him into leaving faster,and my tactic worked he got out of there quickly,and ever since if I got out my bebe gun he would not stay in the house,and it was the best way to get him to leave,I will appreciate all responses I get on this discussion,and just like with all my other discussions I will appreciate all mylotters who take this discussion seriously,and give me honest truthful answers,and as a mylotter I promise to comment on all the responses I get, but my comments will be determined by the quality and the length of each response I get,have a great day.
