Psalm 82 is a psalm about those with whom Jesus by implication in John 10 contrasts himself: Sons of god who are less than worthy of that description, but called it anyway. In John 8, Jesus also describes even less worthy people, despite their self-description as what today would be called by some, ‘the good guys’, Jesus pointed out their inner hatred and lying tendencies as actually akin to sons of Satan. So there are good guys who are evil good guys, and there are sons of God who are not worthy of it. Jesus wants all, even if only good guys in name and not in nature, to not only believe in him, but to hold to his teachings in order to be his true disciples, and thereby become worthy sons of God.
