He was remorseful of what he did.

He's feeling very remorseful,

He's not remorseful,

I am much chastened and profoundly remorseful.

I don't have the sense she's remorseful, because I don't have a sense she knows what she's supposed to remorseful about. She's in shock, absolute shock.

He apologizes to me, but I wish he could apologize to Mr. Barnes himself. He is very remorseful.
