Guillaume kills Horacio "because he was shouting too loud." At his trial, the vacuity of the motive disconcerts. During his 10-year-long stay in prison, Guillaume gradually forgets this story of a guy shouting too loud which convinces no one. When he gets out, someone starts shouting again.
Unfortunately the movie Horacio is not yet available on HBO Max.
