Star Wars Question

I'm fine with the basic plot being that Anakin turns in order to save Padme. I don't like how it was done. It was too sudden. He goes from basically good Jedi to slaughtering a bunch of kids in like 2 minutes. I don't think the sand people scene in Ep2 really counts for much. Also didn't he think just maybe Padme isn't going to want anything to do with me after I turn against the Jedi and slaughter a bunch of kids.
to be fair you could have given hayden christensen 2 years to make that change and it probably wouldn't be all that different
