Answer:
Tempting a black man
Explanation:
“She has committed no crime, she has merely broken a rigid and time-honored code of our society, a code so severe that whoever breaks it is hounded from our midst as unfit to live with. … No code mattered to her before she broke it, but it came crashing down on her afterward.”
Atticus Finch is presenting a fundamental differentiation of how the local society sees its own rules and the actual laws.
Mayella broke the code of society by making advances on a black man. The local society would never accept that a white woman would be interested in Tom Robinson because of his skin color and would hurry to judge him as guilty even though that was no evidence to prove it.
There is no actual logic to it, and that's what made it so hard on the children that tried to think of it logically. Mayella simply broke the social norm when she invited a black man to her house and came on to him. Tom Robinson himself knew that nothing good would come from it and so did she.
