Good in itself

They don't?

In my opinion, not particularly.

If so, why were we given commandments?

I have no idea.

“Keep the commandments of the Lord and His statutes, which I command you today, for your good” (Deuteronomy 10:13). The commandments are for the good of man.

Two notes: 1. This does not mean that this is the purpose of all the commandments (perhaps only some of them are intended to benefit us. For example, those between a person and his fellow man). 2. This does not mean that the commandments themselves are beneficial. Perhaps it is the reward we receive for observing them that will benefit us.
