Comparing Kant's Duty To Divine Law

After all, each of these examples end with the same ... someone loses his life. Sometimes it is one person sometimes more, sometimes it is someone guilty and sometimes someone innocent. And what can be said about lies, scams, etc.? Are election campaigns not a habitat for such practices? These are the people who are running the law, they should obey these laws and give an example to others. The law says, "do not kill", "do not lie" and it is a duty that should be fulfilled. Despite the fact that state law has similar principles to divine law, it is extremely different, because in contrast to God people are imperfect. That is why Kant had the right to say that we should be guided in our lives by reason and by the duty to live morally.
And that
Kant writes this: “For example, it is always a matter of duty that a dealer should not over charge an inexperienced purchaser; and wherever there is much commerce the prudent tradesman does not overcharge, but keeps a fixed price for everyone so that a child buys of him as well as any other. Men are thus honestly served” The seller demonstrates the wisdom which, together with goodwill, obliges us to direct by duty in our lives. So, what is duty? Duty is undertaking something that we do not like, and we do not feel like it, but it should be done; there is a duty and we must do it. According to Kant, a man who does something only because of fear of consequences does not act morally, but if his behavior results from duty, he is moral. For example, if someone borrows money from a bank and pays it only for fear of not giving up money, the Bank will take his property, or he goes to jail for it, according to deontology, such a person does not act morally. However, if this person pays off debt because he has declared himself to do so, then this is the moral proceeding. Kant in his theory pointed out the scope of the morality and marked the difference between moral and immoral behavior, but people are rational beings and should behave in a rational manner. For example, a man who uses reason and the maxim does not kill will care for his life, because he understands this duty and has a natural inclination to it. If his life is successful, he should not have a problem with it, but his maxim of protecting life is not yet moral. The situation changes when someone is not successful in life, and the worries of everyday life overwhelm him so that he loses the desire to live, but out of duty he still protects his life, then his maxim has moral content and his actions are worth imitating. That is why Kant suggests that thanks to reason, people should take actions that could
