to ask a question about truth and lie, which one is good? is the way to promote lie. because the goodness of truth is not questionable irrespective of the situation you are in. whether you are talking about your brother or sister or any other person at all, even about yourself. it is your duty to speak truth and to promote truth and to be the messenger and agent of truth

the truth always prevail! although sometimes, we tend to make "white lies" to make things or situation better - yet it still a lie and not good. do you agree that the only thing impossible to God is to tell a lie?

well "telling the truth may set you free"they say. But sometimes you have to lie for the benifits of other like if your brother commit a crime just to save 20 person would you tell to the authority that he's the criminal.

lie is not good in any case any one who is in favour of lie does not to let the society prosper in harmony

Telling lies is never a good thing.
