What's Freddy's motivation here?
I mean once he's killed Kristen and taken care of the last of the original Bash Street kids.
Beforehand I guess we could all have a little sympathy for Freddy being hunted down and murdered based upon scurrilous rumour without fair trial by that sick rabid pack. Perhaps those parents deserved it for such unbecoming behaviour, who can really say...
However once he's killed Kristen what keeps him going? What gets him out of bed in the morning, ready to face the world without feeling slightly jaded about the prospect of spending yet another day hunting down some gang of 80s high schoolers?
