Is hatred ever a productive thing to have?

[justin]

I think i have held my anger in over the years with somethings and this was because i use to suffer with a bad temper when i was younger and made alot of changes. but i feel i may have been wrong on not letting hatred or anger be the answer to anything. i think it can break me from my chains so to speak. but can be a venom if i let it dwell. it`s hard to know when getting angry or seperating yourself using hatred is appropriate or useful. i sound like a total nutcase i know. but it has been something that i have always thought on. on that fine line between useful and destructful.
