No matter what the situation, there will always be people who ignore morals and values ​​and continue to do what they want, even if it is wrong. The understanding and ethical position of deontology introduces a totally new perspective into the case. It introduces the idea of ​​the principle of universalizability, according to which an act is good only when everyone does the same without exceptions. This specific principle doesn't seem to be valid because everyone disagrees about what the law is and what they think is right. If America had truly banned firearms, not everyone would have agreed. I'm sure we can all agree that it's wrong to kill people. If killing people was a universal law, everyone would be dead, including yourself. There are murderers out there who want to kill all the people in the world before they kill themselves. Their perspective on how the world should be is different from society's perspective. It is difficult to have a universal law that everyone can be satisfied with. Every action you take will hurt someone. You try to solve someone's problem but you create a problem for someone else. If I stopped selling guns, I could solve society's problem, but I would create a new financial problem for myself, even though it might be the right thing to do..
