"There are dragons that are truly dangerous and are best left alone. We should not fall into the trap, so well laid by modern psychotherapy, that seduces us with the idea that every repression can be lifted, every pain healed. It is an over-simplification to see evil as pain turned outwards as hatred. All we apparently need to do is fix the hurt and the evil will go away.... The individual and collective energies, complexes, call them what you will, that can be symbolized as dragons, are extremely powerful and can only be faced at the right time - and not before. And there are some dragons - demons perhaps rather than dragons - which are the result of evil thoughts and deeds and which only the gods can face without harm".
(Note: Negative polarity dragons can come in any color as can positive polarity dragons. I've heard from individuals that have had great relationships with black colored dragons which is quite possible. Just use the same common sense and good judgment with Dragons that you would use in selecting your friends)
