Forgive me, but what is the purpose of drama but catharsis?

I'm a little slow, so forgive me if I'm inarticulate.

Forgive me for not writing but this man is exhausting.

God will forgive me; that's his business.

Forgive me my nonsense as I also forgive the nonsense of those who think they talk sense

Of course God will forgive me; that's His job.
