Why is respect so Important to have in society?

Put it like this

'' Would you like someone to come up to you and say '' HEY YOU! YOU ARE UGLY! ''

That is so rude of them to say.

Would you like someone to come up to you and say that?

Of course not because they could have kept they're rude comment to theirselves.

If they have nothing nice to say, they shouldn't say nothing at all.

That's exactly why respect will not only be important but ALWAYS be important.
