Wrong. Lying is always and everywhere immoral (yes, even when it is understandable and forgivable such as the classic Nazi thought experiment). Not only is it intrinsically immoral as it perverts the functions of speech and communication, but it has long term consequences like the undermining of trust and social relations and the further corruption of the liar's character and the scandalous contribution to a degenerate ethos in society where truth is treated as selectively important. Our present day culture of sophistry and bullshit with its cavalier attitude toward the truth is what you can expect. Mental reservation, on the other hand, is sometimes justified.
