To be honest, I think this is one of the very difficult questions. The main opinion of a person who owns a gun is in 'self-defense'. I agree with that. Owning a gun can stop the other person from attacking you. Also, you should be careful to act because you feel that someone else will own a gun. A lot has happened in Korea recently. There were many cases of using a knife and causing damage to many people. We think that it is the absence of self-defense. If there was a gun, it would be significantly reduced. Of course, I can't help but think about the damage. I don't ignore it. I rather respect it. It's a worry worth considering, and I don't have a good alternative to it either. An alternative that comes to mind is to increase the power of the police, public officials, and public authorities, but since Korea is a country that has experienced dictatorship, that would be difficult.
