I want to know a movie......?

A movie about some kids, possibly a boy and a girl but certainly a boy. Mother is struggling as a single mother. It’s thought the father died in a war. A disfigured man is scary and is kind of a creeper until the end and he protects them and you figure out it was their father who was disfigured in the war and returned but was ashamed to let them know. It’s very " to kill a mockingbird-ish".

80s possibly
