I never understood why people have to lie and deceive. Especially if you consider yourself frum. When someone lies and deceives the majority of the time someone is going to end up seriously hurt. It is not ethical to lie and it is not ethical to deceive and it certainly against the Torah and all Jewish principles. There are times according to halacha that it is permissible to tell a lie or deceive but these are only specific times and the result is not going to be someone hurt. If you are an honest person and try to live an ethical life why do people need to take advantage? Why does this happen?
