I’m told it takes ruthlessness to succeed in what you want to do in life. Probably the ruthlessness implicit in being able to act without regard for ethics or morals. It calls to mind some things I’ve read before, on the use of violence and/or ruthlessness to cow people and make them submit to you. It’s more a mind game than a reality; if you are able to demonstrate to the other that you are willing and able to act without conscience, you will put fear in that person.
That person will fear you, will take needless care and might just slip up, while you remain calm and collected. The threat of force is, of course, much worse than the application of it (though some might dispute this).
