How rude would you say this was?

A regular customer (iin her late 70's) we frequently see at the same supermarket was grieving the loss of her child. Her 51 year-old son died from a sudden cardiac arrest just last week. Someone else really commented that it would've been worse if she would've lost him so early in life, that at least he had a chance to live that long to accomplish some things in life.

Obviously that didn't make that lady feel better. That made her cry more. To her that was still her little boy. If you had to give it a rating, how rude was that comment?
