Juan is a victim. He is bullied by everyone: his parents, Mr. Rage, the other members of the Mafia, himself, his Quifflings, Females, even his own inflatable wife bullies him. Poor guy.
But don't feel too sorry for him, since he is, after all, a member of the Mafia. He summoned an army of Quifflings to aid him in his endeavours, and with Mafia help, he did eventually manage to kill Mr. Rage in the Duel for the Golden Crossbow, but commited Seppuku soon afterwards as both his inflatable Bride and his Crossbow were destroyed.
