So SPOILERS ALERT - Christopher Ecclestone's character basically...
... SPOILERS - started out as the good guy hero, with how he defeated single handedly those two thugs in the loft and saved his and the lives of his two friends. BUT... SPOILERS ALERT...
LATER, he became almost like a brutal serial killer, heavily mutilating their dead bodies but even MORE than that... TURNED AGAINST HIS TWO FRIENDS... OR at least, one of them anyway, in a highly immoral way and...
Basically became a cold hearted VILLAIN at the end no better than those thugs.
Did he become psychotic? Or did he become heavily greedy or BOTH? Was he almost always on the dark side? Or did he suddenly turn especially when financial opportunity known as the large sum of money turned up?
What do we think, thanks.
