When it comes to fighting sin, violence is okay. In fact, we're called to put our sin to death. The Apostle Paul teaches this in Romans 8:13, "For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live."
Don't try to manage your sin, put it to death. As John Owen said, "Be killing sin, or it will be killing you."
