Anakin was hardly a saint. The animated Clone Wars shows him as a bit of a dick from what I've seen/heard, and he was always questioning Obi-wan's training because he was arrogant as smurf. He should not have been told he was the Chosen One; it did nothing for him but fill him with pride. His lightsaber skills were apparently off the wall though so there's that.
But, yeah. Easily corruptible. Jedi only train young children as a rule because they don't want them forming attachments and they want to kill off emotional responses before they take root. Just because we would react in a certain way doesn't mean a Jedi should. They're supposed to be custodians of the galaxy, a source of enlightenment and guidance and protection. Can't do that if they're committing crimes of passion all over the place.
Padme's loss of life is horrible 'cause she was a really cool character but I think we can head canon some of that bulltrout away with this: Anakin's affinity for the Force was so strong, and Padme's mind so susceptible to the image of adorable 9-year-old Ani, that she was unwittingly mind tricked into a sort of Force bond with him. When he "died", her body and mind freaked the smurf out and she could only cling together through the shared pain long enough to pop out a couple kidlings. I mean, Force bonds are explored in both Old Republic games so it's clearly a thing that was thought about.
