My view of being a great Jedi is to have balance. What caused the Old Jedi Order to die out was that they restricted themselves, made themselves more like monks than living beings with needs, feelings and moral judgements. They shouldn't try to shut out what they are, living beings, but rather, embrace them. This is why I loved Luke's New Jedi Order in Legends. They were more unrestricted, they seemed more like individuals rather than beings concerned with a narrow minded view. To be a great Jedi...is to have great power, but not restrict yourself in using it. Especially when the time comes for where you have to use that power to bring down a great threat. But you also have that responsibility to control that power when that threat is gone. You can be loyal to the Jedi and still be a human being, or alien. And that means having a family while being a member as well. With great power, comes great responsibility.
