Who did the Favre to Vikings hurt more - Packers or Lions?

Packers no doubt because he broke the hearts of a community of Green Bay when he went to the Enemy in Minnesota. Don't you know Wisconsin and Minnesota are rivalries in everything. It is like Favre was married to this women for 15 years and then he went and hooked up with the girl that his wife hated the most. I don't know why this would hurt the Lions more because he has been killing the Lions ever since Barry sanders left.
