two sides of the same shield
Two different, contrary, or opposite perspectives about or aspects of something. We fear death because it seems unknown to us, but it and life are really just two sides of the same shield. Thus we can see that arrogance and envy are often two sides of the same shield, both provoking and feeding off of the other.
