Love the Sinful

Our love always leads us to identify with the desires of those whom we care about. If those are not virtuous, we may at first resist them. Eventually we will come to tolerate them. But as time goes on we will rationalize them. Before it's over we may even come to embrace them.

Resist, tolerate, rationalize and embrace.
It is a slippery slope to love someone who does not have virtuous desires in their heart.
