Final answer:
The speaker of "The Fugitive Slave" commits infanticide to assert power and protect the child from slavery.
Step-by-step explanation:
The speaker of "The Fugitive Slave" commits infanticide to assert power over the child. In the poem, the speaker, who is a fugitive slave, kills the child to prevent them from experiencing slavery and its associated hardships.
This act can be seen as a desperate attempt to protect the child from a life of slavery, as enslavement was a brutal experience during that time. By committing infanticide, the speaker takes control over the child's fate and prevents them from being subjected to the cruelty and oppression of slavery.
