Summary
This quote suggests that if someone feels the need to harm or deceive someone else, it is better to do so in a subtle and concealed manner. Rather than directly attacking or betraying them, the quote advises a more indirect approach by pretending to be supportive and friendly, while still serving one's selfish interests. This can be seen as a cunning strategy to achieve one's goals while maintaining a facade of congeniality and avoiding immediate confrontation or suspicion.
