That's pretty much Blade Runner for me. Roy's interogating technicians? Poor Roy! Roy's putting out his master's eyes? Poor Roy!

(I mean, apart from anything else, I doubt that anyone had ever introduced him to the concept murder is wrong. In fact, just the oposite - four years old, and built to kill. And then die before he could become an inconvenience ...)

Exactly. Heck, when Tyrell smugly made his "sorry, old chap, but you're toast anyway, so look at the things you've accomplished as our slave and cheer up!" statement, I was rooting for his demise! Incidentally, at the time I also thought that scene was the best rendition of Frankenstein's Creature, as written by Mary Shelley (as opposed to the movie versions), confronting his maker we had in cinema.

Given that the replicants only had four years and were programmed as killers and sex slaves respectively, the fact they could come up with their own emotions and - Roy at least, in the end when he saves Deckard - ethics is amazing.

Scorpius and Crais: yes, that makes sense.
