It sounds good to love and hate the same person. But how to act towards this individual, practically speaking? This is the time to employ compassion, which banishes hatred and arouses love.  But what about King David's “consummate hatred” towards certain sinners, to those who are aware of the Creator and choose to deny Him? Don’t they have a soul too? Goodness to be loved, no matter their sins? Yes, but their Divine spark is hidden into obscurity, so that not even a glimmer of soul is revealed. With a lost signal, love might be quite elusive.
