Whether quarreling is a more grievous sin than flattery?

Objections

Objection 1 : It seems that quarreling is a less grievous sin than the contrary vice, viz. adulation or flattery. For the more harm a sin does the more grievous it seems to be. Now flattery does more harm than quarreling, for it is written (Is. 3:12): "O My people, they that call thee blessed, the same deceive thee, and destroy the way of thy steps." Therefore flattery is a more grievous sin than quarreling.
Objection 2 : Further, there appears to be a certain amount of deceit in flattery, since the flatterer says one thing, and thinks another: whereas the quarrelsome man is without deceit, for he contradicts openly. Now he that sins deceitfully is a viler man, according to the Philosopher (Ethic. vii, 6). Therefore flattery is a more grievous sin than quarreling.
Objection 3 : Further, shame is fear of what is vile, according to the Philosopher (Ethic. iv, 9). But a man is more ashamed to be a flatterer than a quarreler. Therefore quarreling is a less grievous sin than flattery.
