MiddlePath-
Btw, thanx for the compliment 🙂
I am doing a good deed because I love G-d, and want to show my love by following His commands.
While in principle I agree with this, I believe it is an oversimplification.
One might say that the purpose of not murdering your friend when you are angry is to show your love to God. On some level this is true, but not directly. Allow me to explain.
