Falci: But I don't think it would be unthinkable that the son of a man, who was led to believe he was the most legendary absolutely powerful being in the universe from a young age (and yet be powerless to save his mother), who murdered absolutely everyone and everything he knew and loved, including children, because he had a bunch of bad dreams about his wife and child dying, would consider in any way a valid option to kill the nephew he's being training and nurturing from a young age, because he had a bad feeling the spoiled little brat would turn evil.
Breja: I think given what we've seen of Luke in the original trilogy it's entirely unthinkable. After everything Vder did, he saw good in him. He refused to strike down even the Emperor himself in anger. And now he would consider killing an as-of-yet innocent kid? No way.
Now, with some skillful writing and enough time it might perhaps be possible to bring Luke to that point. But presenting it to us as a done deal like that? And after they did have a whole previous movie they could have used for that, but instead they wasted it on remaking A New Hope? Nope. Sorry. That's just bad writing.

You know what, I watched the scene again, turns out we're both wrong. Luke went in to check the darkness he had sensed in Ben's heart and was scared shit to realize that it was already all dark. He reacted by instinctively lighting up his lightsaber. As he realized "Dude, what the fuck you're doing?" and became ashamed, his nephew woke up and saw only his uncle trying to murder him. Which is exactly what the audience seems to have seen as well. XD Less lazy writing, more lazy watching.
And, hey, if he could beat the crap out of the dad he was trying to save before coming to his senses and throwing his light saber away, he could easily had a bad reaction to his nephew's internal darkness before coming to his senses and turning the damned thing off.
Anyway, about Masters of the Universe, I think we may get to see something close to the Intergalactic Skeletor figure from the MotU Classics series (itself based on Skeletor's look at the start of The New Adventures of He-man). It occurred to me because I remembered seeing that figure and the bio ir comes with online some time ago (and checked and confirmed again) and it was a more cybernetic Skeletor who had healed himself after a battle with Hordak using some sort of technovirus. And, guess what, we have a technovirus subplot going on in the show as well. But I don't think we'll get Hordak, though.
Now... I'm not really excited to see ponytail and jeans He-man in the show (the figure itself is Galactic Protector He-man), but I think it could work as an older and better trained Adam. The figure's bio described itself as He-man after Adam had decided to abandon his original identity and become He-man permanently.
Well, we'll see. :)
