孤独成罪我对人心早有防备
[gū dú chéng zuì wŏ duì rén xīn zăo yŏu fáng bèi]
Meaning 'loneliness is a sin; I've always been wary of human hearts.' This indicates a belief in isolation as painful yet deserved due to perceived flaws. Also, there's an acknowledgment of being cautious towards others, anticipating possible betrayals or disappointments.
