Boba Fett embodied the criminal underworld he could not escape. Han even referenced "that bounty hunter back on..." when we first see him in Echo Base, establsihing he's chasing him from the beginning. Not to mention Boba Fett doesn't fit into the whole "black and white clear cut heroes and villains of Star Wars". He represents the lawless, the grey, he's a character that a lot can certainly be done many things with.
