What are 3 examples of the evils of slavery other than physical violence in Douglass's Narrative?

To add on
to some of the suggestions in the earlier post citing Douglass's narrative, consider also the
damaging psychological effects that the institution of slavery had on people.  When Douglass
makes his initial attempt to escape with a group of other slaves from his plantation, the
authorities are notified and the plan is botched.  Slaves suffered from extreme fear, and
Douglass explores various manifestations of fear throughout his narrative.
