The Pharisee paints the tax collector as evil, but the pharisee is the bad guy in this story. Literally the next two verses:

13 But the tax collector, standing some distance away, was even unwilling to raise his eyes toward heaven, but was beating his chest, saying, ‘God, be merciful to me, the sinner!’ 14 I tell you, this man went to his house justified rather than the other one; for everyone who exalts himself will be humbled, but the one who humbles himself will be exalted.”
