It's not a good thing Jealousy can lead to many bad things no matter what it's over. It feels like having poison in your veins and while I agree that small jealousy isn't a big problem, serious jealousy as a whole is bad. People need to learn to be grateful for what they have because they could have nothing or what they do have could be taken away from them. Jealousy is a natural thing, but that doesn't make it something we should be proud to have.
