Committing a Crime vs Committing a Sin

If you had watched a recent movie on Laughing Kor (Laughing Brother), there's a distinction made btw Committing a 'crime' (fan4 fa3) vs committing a 'sin' (fan4 zui4). Just because you have committed a crime need not mean automatically that you have committed a sin. Eg. if you steal bread from a shop to feed your starving child, you are deemed to have committed a crime in the eyes of the law, but in the eyes of God or your conscience, this 'crime' is not a sin.

Contrary to our general perception, the law is not exactly perfect. Think controversial, unfair, outdated, discriminatory laws....Other than the Section 377A of the penal code shown in an earlier post, here are 2 more examples of problematic laws:

Article 1(a) Article 1(b) cont'd

Article 2:

Qns:

-Should the law always be obeyed?

-Is it ever acceptable to break the law? (HCI)
-Justice is always served whenever the law is upheld. Do you agree?
