He wasn't a mugger....if you watch the whole thing it sets the story like this:
He created her, breathed life into her, showed her how to move, made a tree and got an apple for her to eat, and is dancing with her...then the other guy cuts in (this is a portrayal of romantic relationships), and dances with her for awhile, then cuts her loose...the black guy comes and is flashing money, she starts trying ot get the money...then the party girl comes in and starts her partying, then the skinny model girl comes in and she starts making herself throw up to be skinnier, then the cutting/death guy comes...and this whole time each thing that comes just moves her further away from Jesus...and when she finally realizes that she just tries to get back to him, but all those things and people in the way are trying to just drag her down and keep her there...and if you watch him he's in the background trying to get her attention, and then when she's trying to get to him, he's pulling for her...and finally he just can't stand to watch her getting beat up and held down, so he goes in and takes all the violence and shields her, and finally throws them off...because all he wanted was to dance and spend time with her.
