Using Anakin from the PT is just not going. That Anakin was a complete idiot. No sane, hell, remotely sane person goes off an kills a whole bunch of kids (we're talking like 5 year olds), teens, young adults, and adults because someone who might be able to maybe save his wife tells him too. That's a whole other botched storyline.
Again, you don't get to the edge of maybe killing your nephew because your vision says he kills everyone you care about - then set him on that path and leave them to fend for themselves. It's not to say luke doesn't struggle with things in his life, but that would not be one of them. After that, it'd be more important than ever to protect those he cared about from the danger he theoretically just unleashed. And to be blunt, part of the problem is we do not know that Kylo is born BECAUSE of Luke. I'd say it's a 99% likelihood that Snoke with messing with his head early on. Your uncle looking like he's going to kill you in them middle of the night doesn't send you from happy-go-lucky, nice guy jedi, to evil, passive aggressive super villain.
When you do this in a movie it has to have everything thing contained in the movie for audiences to accept what you do. The whole thing is contingent upon looking acting irrationally over a vision he knows isn't necessarily true - for which the audience has zero basis to believe that vision. You want to compare to to Luke going to Bespin to try and HELP his friends. He didn't go to face Darth Vader, or kill him, or anything of the sort. He went to try and help his friends. Period. The only 'history' we have of Luke acting on a vision is of him going to help his friends. Sure, you can try and spin killing your nephew as helping your other friends, but it'd be much easier to prevent him from going evil in other ways. If he's going to make he huge leap from one vision to killing his nephew, there's gotta be a whole lot that takes place prior to that to make it even a remote possibility. We don't see any of it which makes the whole thing pretty unbelievable to the view. It should tell you something that you're the only one who thinks it's believable.
