I completely disagree with this quote because I believe that responding with violence, like Christopher did when he knew his father had lied to him, under any circumstances is not acceptable.
First, I believe that violence is not acceptable because I think that when people act violent, others get hurt in the way. Just to give the simplest example possible, if for example, in one of the school’s classes somebody hits another, and there is no proof of who started the fight, then both would be punished, which means that an innocent got hurt from a violent action. Instead, if they would have made a debate, then they would have never been punished and it would be clear who is wrong. Another example is World War Two, when millions of Russian soldiers died to save their country, yet Stalin, the dictator who led them, did not even get scratched. Here, the person who deserves to be hurt was not, yet the innocent soldiers were either killed or disabled.
Also, violence does not solve any problem. For example, when Christopher and his father fought, nothing changed from the fact that his father lied, their feelings toward each other just became worse and they just hurt each other. Another example is war, when two armies just kill each other mindlessly, and then the two countries sign a treaty. Here, the problem was not solved until both countries accepted that violence would only hurt them and would never give them what they wanted, so they try to reach to a fair ground. It would be cheaper in both money and people if they solve their problems from the beginning in the correct way.
To sum up, I think that violence is not a right way to react to any problem, both because it does not solve any problem and because it hurts the wrong people most of the time.
