心软是病怎能与你为敌
[xīn ruăn shì bìng zĕn néng yŭ nĭ wéi dí]
Expressing the idea that being soft-hearted or too kind can be a flaw that makes confrontation difficult, as if compassion itself is an ailment that renders them unable to oppose others, especially the addressed 'you'. This may imply feelings of being exploited or hurt due to one's forgiving nature.
