It all depends on your perception ! =)

No. its the greatest gift of creator that doesnt even follow the rules of this world But it becomes lie someday if its was not pure :-) (if it was fully based on material things like needs, sex etc)

it depends on the kind of love , when parents love their kids that is not a lie , when you love your daughter that's not a lie , when you love your wife that (may be ) a lie -just kidding- , what can be a real lie , is your girlfriend , she isn't really a person you are bonded with , she can leave you when she or you is bored , it's really a disgusting relationship between man and woman.

I don´t think so at all, but that´s a question everybody has to judge on his own.
