Everything he did was easily justifiable as it's happened mainly to undesirables and he was a judge, and had the authority to do a lot. He pushed away the archdeacon who was a good man able to see that beyond his veil of self righteousness Frollo actions weren't good ones, but I doubt he had the authority to do much about it.
Also excommunication was mainly a political tool and one reserved for clear heresies, you don't excommunicate a murder.
Still, bells of Notre Dame basically spells everything out:
>Judge Claude Frollo longed>To purge the world>Of vice and sin>And he saw corruption>Ev'rywhere>Except within[...]
[Archdeacon, sung]
>See there the innocent blood you have spilt>On the steps of Notre Dame[Frollo, spoken]
>I am guiltless. She ran, I pursued[Archdeacon, sung]
>Now you would add this child's blood to your guilt>On the steps of Notre Dame[Frollo, spoken]
>My conscience is clear![Archdeacon, sung]
>You can lie to yourself and your minions>You can claim that you haven't a qualm>But you never can run from>Nor hide what you've done from the eyes>The very eyes of Notre Dame[Clopin]
>And for one time in his life>Of power and control>Frollo felt a twinge of fear>For his immortal soul
