Really there is no cut n dry answer on their temperaments. The reason being is that each snake is different. Some tolerate human contact and some do not. It's has nothing to with if the snake is normal, tiger, albino or whatever. I've own some mean a$$ albinos and one tiger that would try and kill you.
Most rude baby Retics turn into sweet adults but that is not a garuantee. Just keep handling her after her acclimation to her new home and hope for the best. Most tame down once they pass the three to four foot mark.
As far as feeding her inside the cage:
To me this really isn't a great idea. They learn very quickly that when that cage door is opened food is coming and that's when some bad accidental bites happen. Yes .......... even when using hooks. Several times I've seen a good sized Retic over shoot the hook and get the keepers hand. Start training your little kid now. On feeding day pick her up with a hook and put her into a locking lid rubbermaid container. Once she's eaten then gently lift her back into her cage. Granted if she reaches a large size this will be extremely hard to do. But so far this "training" has worked extremely well for me and several other keepers of the large python species.
Here is a link to a care sheet on Retics written by NERD. I suggest you print it out.
