It is no mastery to watch and fast till thy head ache; nor to run to Rome or Jerusalem on pilgrimage upon thy bare feet; nor for to stir about and preach, as if thou wouldst turn all men by thy preaching. Nor is it any mastery to build churches or chapels, or to feed poor men and build hospitals. But it is a mastery for a man to love his neighbour in charity, and wisely hate his sin, and love the man. (John Climacus)

Neither Deuteronomy nor Jesus diectly reference hating our neighbors sin.

Instead we are to love God with all our heart, soul, and mind and our neighbor as ourselves. All the rest is commentary.

More than any specific deed, it is the relationship with our neighbor that establishes our relationship with God.
