User blog:XD1/Eclipse Script: To read, or not to read?

So, a friend has sent me a xeroxed copy of Jackson Rathbone's copy of the complete script for Eclipse (film).

Quite the moral dilemma. Is it wrong to read it? I'm not doing any harm to anyone but myself, in the form of a minor spoiler, since I'm planning to go see the movie regardless, and I've already read the books...
