"Exculpate" is a word I really need to remember more in English. Sometimes I want the sense of "disculparse" and "unguilt" doesn't exist in English.
I was talking about the great contrast between the hooded figures singing "mea culpa, mea culpa, mea maxima culpa" and Frollo saying "it's not my fault" in "Hellfire".
They say "mea culpa" while he tries to deny his culpability.
