If passion drives you, let reason take the reigns. Attacking people out of jealousy is a devaluation reaction. The passion of anger and emotional is rooted in fear. It would seem that a person who is free of jealousy is free of fear, but I would not describe this as a mindless state, but rather, intelligence functioning at a high level.
Aristotle made a distinction between envy and jealousy. He considered jealousy reasonable, because it drives men to pursue good things that other men have. Envy is much worse, as it causes men to destroy the good things other men have, or, at bottom, an envious person will try to hold you back. Jealousy really isn't that bad as long as you’re just sticking within your own boundaries.
If you want to enjoy yourself, build a good life for yourself, have a firm foundation, make the necessary preparations, and jealousy won’t be a problem. Envy helps to, or is perhaps the very source of, our ambition and progress in life. It helps us fix our minds and it basically makes capitalism work. So although envy isn't exactly right morally, it is very, very useful. The root of being envy is wanting something you don't have, which only means your discontent is some aspect of your life to consider being envious in the first place.
