Where's My Anger??

It's been 40 days NC.
I've read, asked questions here, processed, grieved.
I feel I have a much clearer understanding of the abuser and what happened to me.
I feel ashamed, horrified, mortified, and devastated.
Shouldn't I be feeling anger at this point?
I will never ever have contact with him again, I'm sure. He almost destroyed my life. I will not allow myself to ever respond to any form of communication, no matter if his dog is dying (I love his dogs)
But, what I feel mostly is compassion; sadness and pity for him that he is an empty shell and doesn't even know it.
I'm just very worried because if anger is a normal and valuable stage, what's wrong with me?
