Briefly describe Hiram's argument for testifying and Grampa's argument against testifying. What type of conflict is this?

Grampa argues that testifying might put Hiram in danger. He notes that Hiram didn't actually witness the crime, and that all he'd heard was just R.C. talking about it. Grampa then says that Emmett got what he deserved, and his last argument is based upon his not wanting Hiram to embarrassment the family.

Hiram. however, sticks to his guns and say he has to do what is right.
