I do agree with most everything of what you had to say, but not the implication that how we behave is genetic and not a matter of choice. Our environments during our formative years is probably the major underlying cause of how we relate to one another. However, in the end, it is up to our own choosing.

Just as Jesus chose to come into the world and His choosing of giving His life to save others.- that is to say - everyone who would choose to accept Him into their lives.
