Gradual aging? Would it be something you'd like to see in future instalments of the Sims?

I'd rather sims receive all traits from the beginning. Makes no sense that a sim can suddenly be evil upon aging up to adulthood, for example.

Maybe if they were a neglected teen with a bad circle of friends they could grow up to be evil. I think some traits can be shaped and trained one way or another, for better or for worse. Like if you encourage a slob sim to be neat and clean often enough, they might develop their neat trait. Some traits could be inborn and some could be acquired through gameplay.
