To show mercy to the wicked is cruelty to the good; to pardon oppressors is injustice to the poor.
When you care for a scoundrel and treat him kindly,
he uses your favor to sin as if you were his partner in it.
Explanation: The phrase about sinning 'as a partner' means the wicked person exploits your generosity, making you complicit in his wrongdoing.
