Final answer:
Both instances involve betrayal and violence, enhance the theme of hopelessness, and are crucial to the plot and character development.
Step-by-step explanation:
The commonalities between Killer Kane's attempt to murder Loretta Lee and the murder of Max's mom lie in the elements of betrayal and violence present in both instances. In the narratives, these actions reflect the desperation and malevolence of the characters involved, intensifying the theme of hopelessness.
In both the attempted murder of Loretta Lee by Killer Kane and the murder of Max's mom in the book 'Freak the Mighty', two things in common are the element of danger and the presence of a powerful antagonist.
Additionally, both instances drive the plot forward, creating pivotal moments that significantly affect the main characters' development and the story's trajectory.
