Step-by-step explanation:
The question pertains to the comparison between two characters, Andrew Wiggin (more commonly known as Ender) from 'Ender's Game' and Libo from 'Speaker for the Dead', both works by Orson Scott Card. Miro discovers that both Andrew Wiggin and Libo share a deep respect and empathy for other life forms, particularly those that are not understood by others. Both characters strive to understand and communicate with alien species. They possess a unique ability to empathize with the 'other', and this forms a crucial part of their character. Additionally, they have a relationship with the Pequeninos, an alien species in the novel 'Speaker for the Dead'. Both characters also suffer because of their deep understanding and connections with these aliens, facing moral dilemmas and bearing the weight of consequences from interactions with them.
