There is a way that seems right but the end thereof leads to...

Here is a good quote from Chris Green's excellent guide to preaching and teaching from Acts:

"Please do not underestimate the danger of false teaching. False teaching may teach many different things, fake many different things, and take numerous cultural and social forms, but in one aspect it is always identical: it leads to hell. And the flock follows the wolf in sheep's clothing all the way. False teaching is perilous, deadly, poisonous stuff".
