Bah. Hate is an incredibly useful weapon in the short run. Just not your own. However, turn allies upon on another, and you merely have to pick up the remains. Use someones hate as a carrot. A person's hate may be directed to an outside threat, yourself, or themselves. Either way, that hate can be used to direct their actions.
Throw a string of biting insults at someone who hates you and likely they'll charge. But as an animal. Animals make easier meals than men.
In the "New Jedi Order" books, one of the Jedi Masters that survived the Jedi "cleansing" and lived to tutor Jacen Solo, was Vergere. She became a Grey Jedi & worked with Count Dooku and was trained by Darth Sidious as a Sith Adept. She tried to kill Sidious but failed and escaped, so she's pretty good (& by good I mean bad ***).
She made strong points about emotion, that Anger isn't bad, it's natural. Rage is undesirable since it's uncontrolled. Fear isn't bad, it's natural & often helpful. Terror is undesirable since it's uncontrolled. She's at least on par with Yoda as far as power levels go (smashing huge ships together with her mind, stuff like that. She give Luke headaches when he tries to grill her on her understanding of the Force, and she uses torture to bring Jacen to a greater understanding of the Force, basically shortcutting around the long Padewan tutoring process.)
If you want a new experience of the Force & the "new" understanding that healthy emotions are a part of the Force, read "Traitor" by Matt Stover. It's brilliant, & most stores don't have it, it always sells. Order it.
