Good afternoon.
I would suggest beginning by finding the instances within each work that you think show the character's self-respect. Once you have a list of the situations displaying this trait it will probably be much easier to see their similarities and differences.
I also suggest doing an internet search using the title and the keyword "self respect" to see what resources are already out there for these two works and this trait.
I hope this helps.
