Leadership that heals & doesn't enable?

To enable someone means you make it possible for them to be able to do a certain behavior or to think a certain way. Through how you interact with them, what you say, what you encourage or discourage in them, etc, you make it possible for them to grow in a good and healthy direction. The opposite is also true in that you can can also encourage them to move along a path that is unhealthy or even bad or sinful through what you say, do, accept, etc.
When you think about being a leader in the church, what are things that you see in yourself or in other leaders to that paves the way for (or enables) good following/followers? And vice versa, what are some things that you see that enable people in church to continue in a lifestyle of sin or perhaps at least 'ignorant bliss' about their non-Christlike lifestyle?
