How does Max feel about people mentioning his resemblance to his father in Freak the Mighty?

Max's
father is known as "Killer Kane." At the beginning of the story, he is in prison for
murdering Max's mother. He has an infamous, frightening reputation, and Max, unfortunately,
looks a lot like him.

In chapter 1, Max overhears his maternal grandparents,
Grim and Gram, talking about how he, Max, is "getting to look like
Him," meaning his father. Grim also says that the resemblance is more
than physical, and that Max, ominously, is "like" his father in
terms of his personality. Max doesn't explicitly reveal how these comparisons make him feel,
but, as mentioned later in the novel in chapter 5, Grim and Gram clearly and unsurprisingly
think that Max's father was "sick in the head." One can infer, therefore, that Max
doesn't feel particularly flattered or pleased with the comparisons.

In
chapter 5, Gwen remarks upon the fact that Max is "the spitting image" of his father.
Max says that this ordinarily wouldn't be "such a big deal," but because his father is
in prison, it is a "big deal." However, it is only a "big deal" because
everybody else seems embarrassed on his behalf and "acts like
it," meaning that his father's imprisonment "should be a secret."

In short, Max doesn't seem to be especially bothered about his resemblance to his
father. It is perhaps not something that he is particularly pleased about but neither is it
something which he seems to worry about. The only time when it becomes "a big deal" is
when other people feel embarrassed for him.
