The quotation refers to the canonization of the young Maria Goretti who was brutally murdered at the age of 11, when she refused to lie down and have sex with a man who tried to r4p3 her. Maria Goretti fought against his attacker while shouting that he would rather die than practice this sin, which caused his attacker to deliver 11 knife blows against the girl who struck his vital organs and caused his death. Because of her courage to protect her chastity and turn away from sin even in such a violent moment, she was canonized. As Christian principles say that every being who serves God must forgive his enemies and those who do him wrong, people believed that Mary had forgiven her attacker and therefore would like him to observe his canonization with her mother.
The quote questions if this was not too much. And if her killer should even receive this act of human compassion. Even canonized Maria Goretti was a human being who did not wish to die so violently, moreover, this act of kindness and Christian faith may have provided a very frustrating and traumatic moment for Maria's mother who had to accompany the ceremony alongside someone who did her daughter so badly.
