In "Ender's Game," Peter's words at the side of Ender's bed in the second chapter show us that he is a complex character with both good and bad qualities. On the one hand, Peter expresses concern for his younger brother Ender and seems to genuinely care about him. However, his words also reveal a manipulative streak and a desire for power and control. Peter tells Ender that he needs to be strong and not let anyone push him around, but he also encourages him to use violence to achieve his goals. This suggests that Peter himself may have a tendency towards aggression and a lack of empathy for others. Overall, Peter's words show us that he is a complicated character with a mix of positive and negative traits.
