And the fact that he chose to resort to stealing his very first Pokémon instead of catching it or recieving it from someone hints towards a bad upbringing (that and the fact that he is possibly a sociopath). You know he is not a criminal by choice though, as he is very clear about his views on Team Rocket. He probably just had a rough childhood. All of this stuff you can infer from his actions, which is incredible writing and worldbuilding.
Silver should be the golden standard for character writing, not just in Pokémon, but in all of gaming.
