Is It OK to Lies to Get to What You Think Is a Good End?

Is it okay if the means lead to a good end? I mean, just think of so many different things. And what's interesting is that things will pop out, especially after reading different books. After having read the LBJ series and then coming to the New Testament again, I came across the Sermon on the Mount. It says, by their fruits, you shall know them. A bad tree cannot bring forth good fruit. So a bad means cannot bring forth a good end.
