If you could un-invent something, what would it be?

The thing I would like to un-invent isn’t an item but a trait, characteristic, or habit. Call it whatever you want. That, I call it, is jealousy. Jealousy is the root of all evil and the seed of disputes, misunderstandings, and unhappiness. Moreover, jealousy brings to light our bad side and leads us to do evil things. Unfortunately, as normal humans, we tend to be weak and inclined to succumb, some more easily, others not so, to the evil habit of jealousy. I won’t believe it if anyone tells me he/she hadn’t at least felt some tiny jealousy once in a lifetime.

For that reason, if I had a magical stick and could vanish one thing in this world, that would be jealousy. And for one thing, I’m sure we all would be much happier since peace and sociability would lie over this world.
