大般涅槃經義記 6.350

6.350

問曰：若知悉無罪者，云何佛說眾生有罪？釋言：眾生所有罪者，別由惡心，不由知殺。若無惡心，雖復知殺而無有罪。佛今斥就知殺義邊，所以言無。惡心教殺非今無罪，故下如來別教滅除。舉喻類中，先舉其喻，如人知酒，不飲不醉，亦如知火，不觸不燒。下將類王，「王亦如是，雖復知殺」，若無殺意，云何有罪？

Question: If knowing is entirely without guilt, why does the Buddha say that sentient beings have guilt? Explanation: The guilt possessed by sentient beings is specifically due to an evil mind, not due to knowing killing. If there is no evil mind, even though one knows killing, one is without guilt. The Buddha now points strictly to the aspect of the meaning of knowing killing; that is why he says it is absent. Instructing killing with an evil mind is not [said to be] without guilt here; therefore, below, the Tathāgata separately teaches its eradication. In adducing a metaphor as an analogy, it first adduces the metaphor: just as a person who knows wine does not get drunk if he does not drink it, and just as one who knows fire is not burned if he does not touch it. Below, it compares this to the king: "The king is also like this; although he knows killing," if he has no intention to kill, how could he have guilt?
