What is the difference between irony and sarcasm ?

An irony is a statement that, when taken in context, may actually mean something different from, or the opposite of, what is written literally; the use of words expressing something other than their literal intention, often in a humorous context.

While

Sarcasm is the use of acerbic language to mock or convey contempt, often using irony and (in speech) often marked by overemphasis and a sneering or snarky tone of voice.

Sarcasm is the lowest form of wit.

to kill a mockingbird basically is about a lawyer who goes against everything in a racist society like at the time of this novel, to defend a black man accused of sexual abuse. in the bible there are cases like that of joseph, who was accused by the woman of potifar, for a crime similar to that of tim robbinson, of that novel (genesis 39: 1-20). at this point we see that god also provides the escape to joseph, who was accused unjustly, but in his time, and through his attitude, his faith was not shaken, and god provided the solution. the perspective of god also written in the bible and not pay evil with evil. (ephesians 4: 32, 1 thessalonians 5: 15, 1 peter 3: 9). atticus, the lawyer, demonstrated during this lee novel, empathy, love of neighbor, understood the situation of this accused man. he went against everything in that society, and stood in favor of that man, for the injustice committed. this shows the empathy, the love taught by christ, in some passages that speak of love and justice in the sermon of the beatitudes (especially verses 6 and 7 of matthew 5).
