Angel始终如一Devil至死不渝
[angel shĭ zhōng rú yī devil zhì sĭ bù yú]
Translated as 'Angel always stays the same while Devil never gives up until death'. This indicates a contrast between an Angel representing purity, constancy, and goodness; while Devil symbolizes defiance, consistency in adversity or immorality to the last. The netizen wants to show duality within the self: can be kind and evil at the same time or sometimes changes his/her mind from one to the other.
