I believe if one takes a decision by his heart, it would not lead to any wrong direction. But if he failed to listen to his own heart, the path may turn into a hellish one.
And the only reason why one could fail listen to his own heart, is because he is confusing. By the dogmas, by the traditions, by the norms. By anything that divides this world into black and white, into right and wrong.
Anything that would not let him entering the forbidden path, which perhaps never even an existence in reallity.
Listen to your heart honestly, then you may see what are the actual forbidden paths, which the by nature, you won't take those paths.
