Is a "dislike" button really necessary in Facebook?

In my opinion, I don't think it's really necessary though lots of people on Facebook want it. I mean, why would you "dislike" peoples' statuses or photos? It's better if you just ignore it . Hide it if you will. If the "dislike" button was really created, Facebook will be in a disaster by now. For example, a friend of yours posted a status about.. something. Hahaha. Here's a good example!

If there was a "dislike" and some did dislike it, I'll get offended and it'll hurt my feelings. Wouldn't it hurt yours if someone dislikes your photo/statuses? Probably, you'll end up disliking the person instead! I know most of the people wants the "dislike" button but I don't think the Facebook developers would install it anytime soon. Do you even want to post your photos and statuses up and people end up disliking them? Go figure.
