Can Serena truly be forgive for her sins?

Should Serena be forgiven for her sins?

While I am glad that Joy is given a redemption arc in the last couple of seasons, I have to ask, can she truly be forgiven? Why does she get to keep her child when she caused the separation of family, rape, and slavery (these are just the top of my head) and more horrible things to innocent people. She helped create Gilead, she stood there and watch mothers be torn from their families. She watched people be killed for not conforming to her people ways. She even threaten Hannah in front of June (I know that was season one but I still can't get over that one). And after all of that, she can keep her baby?

I just want to know, why should we give her grace?
