Facebook is thinking the way to express more appropriate emotions like “sad”. Mark Zuckerberg said that many user didn’t feel “like” button was appropriate for unfortunate incidents. However, user can comment on a post when they don’t want to use “like” button. And Facebook has no plan to make “dislike” button.

I think that Facebook should introduce another button, but “dislike” is not proper. It means “not like”. No one would push the button when he or she sees the post about death or illness. If people face unfortunate events, they will sympathize. So to express this emotion, “sad” button is better than “dislike” button.

Other social network services also use button to express feelings. LINE is the most famous SNS in Japan, and it has timeline. By using face fonts, user can express many kinds of feeling in timeline. There are six face fonts, love, very happy, good, wish, surprise, and sad. This way is very easy to express how he or she thinks. Not only letters button but face fonts is a good choice, I think.
